1 Tekla Structures 11.1 Common features

Tekla Structures version 11.1 is a main release and contains many new features and fixes.

Compatibility Tekla Structures 11.1 is compatible with all previous versions. You can open and work with existing models using Tekla Structures 11.1.

We recommend that you complete any models you have started using your cur-rent version.

Installing Tekla Structures setup creates a new subfolder for Tekla Structures 11.1.

You need Windows Administrator rights to install Tekla Structures 11.1. This ensures that all Windows system folder *.dll files are updated.

Topics This chapter is divided into following sections:

• General (p. 8)• Modeling (p. 11)• Drawings (p. 26)• Import and export (p. 45)• Custom components (p. 46)• Components (p. 50)

Once you save a model in Tekla Structures 11.1, you can open it in Tekla Structures 11.0, but not in older versions, in Xsteel, or in Xengineer.

Release Notes 7Tekla Structures 11.1 Common features

1.1 GeneralThis section describes the following new features and fixes:

Recording and running macrosIn Tekla Structures 11.1 you can record user interface macros to simplify some tasks that need many mouse clicks. You can record series of actions from menus, dialog boxes and shortcuts.

To record a macro:

1. Click Tools > Macros... to open the Macros dialog box.

2. Type in a name for the macro.

3. Click Record.

4. Perform the commands in the user interface.

5. Click Stop to stop recording.

6. To perform the recorded macro, select the macro and click Run.

8 Release NotesTekla Structures 11.1 Common features

The recorded macros are saved as *.cs files, in ../environments/country-independent/macros folder:

To view and edit the recorded macro:

1. First check that the file type .cs is associated with suitable text editor.

2. In Tekla Structures, click Edit on the Macros dialog box, and the file is opened in the associated editor.

To create a macro file manually, click Create in the Macros dialog box. This com-mand creates an empty macro file, which you can manually edit, or copy and paste macros from other files.

Coordinate symbol in rendered view Now you can see the model direction easier with the new coordinate symbol, located in the lower right corner of the model view. The coordinate symbol fol-lows the workplane.

Disable Advanced options dialog boxYou can disable the Advanced options dialog box so that the variables can be edited in the batch files only.

To disable the dialog box, set the following variable in the batch file:

set XS_DISABLE_ADVANCED_OPTIONS=TRUE

The recorded macro is saved in drawings or modeling folder, depend-ing on in which mode the macro was recorded.


Miscellaneous Tekla Structures 11.1 includes following new features and fixes:

Cursor line width Set the cursor line width in rendered views with variable XS_RENDERED_CURSOR_LINE_WIDTH:

1. Click Tools > Advanced options, and go to the Model view category.

2. Enter cursor line width in the Value field.

• Possible values are 1, 2, or 4. Any other value is handled as 1.• Default value is 2.• Any other number will be treated as 1.

3. Click Apply and OK.

4. You need to restart Tekla Structures before the change is applied.

Fixes • In single user mode, if you open a model in Tekla Structures Viewer,

the model is no longer locked. You can open locked models in the Viewer, in single user mode.

• When the orthogonal snapping was on, picking the first position was sometimes difficult. Now the reference point handling is disabled when starting a command and enabled after picking the first position.

Cursor line width is 1 Cursor line width is 4


1.2 ModelingThis section describes the following new features and fixes:

Adding surface treatment to partsTekla Structures 11.1 includes following improvements in adding surface treat-ment to objects:

Cuts and recesses

Now when you add surface treatment to parts with openings or recesses, select Cut by father part cuts checkbox in the Surfacing properties dialog box.

When you select this option, Tekla Structures recognizes the openings and recesses in the part.

Add surface treatment to cut faces

You can now add surface treatment to cut faces (faces created by a cut).

To add surface treatment to cut faces:

1. Click the Create face surfacing or Create polygon surfacing icon.

2. Pick the origin of the surface treatment.

3. Pick the direction.

4. Select the cut face to apply the surface treatment to:


5. If you chose polygon surface treatment, continue picking the polygonal area.

• Surface treatment added to cut faces is modifed according to the changes made to the part.

Add face surface treatment

In Tekla Structures 11.1 you can apply the surface treatment to parts in the fol-lowing ways:

1. Click the Create face surfacing icon


3. Pick the direction of the surface treatment.

4. Select the part faces to apply the surface treatment to.

• Pick faces one by one, or use window selection:

• Drag the mouse from left to right to select all faces totally within that rectangular area:


• Drag the mouse from right to left to select all objects totally or partly within that rectangular area:

Add polygon surface treatment

1. Click the Create polygon surfacing icon


3. Pick the direction of the surface treatment.

4. Pick the part face to add the surface treatment to.

5. Pick points to form the surface treatment area.

• If you pick points outside the part face, the surface treatment is forced to fit inside the face:

• If all corner points of the surface treatment are not on the part face plane, the corner points are forced to a face of the part.


Overlapping surface treatments

When you create overlapping surface treatments, the smaller surface treatment overrides the larger one.

The overriding is recognized in reports (only the visible area is calculated).

Numbering Surface treatment is now considered in numbering:

To set Tekla Structures compare surface treatment in numbering click Setup > Numbering... , and select Surfacings checkbox on the Numbering tab.

Cutting surface treatment

Use variable XS_POLYGON_CUT_EXTRA_THICKNESS to define the cut depth of polygon cut, for example, to be able to cut thick surface treatment with polygon cut command:

1. Click Tools > Advanced options..., and go to the Modeling category.

2. Set the cut thickness with variable XS_POLYGON_CUT_EXTRA_THICKNESS. The default value is 5.0.

Parametric sketching improvementsTekla Structures 11.1 includes following new features and fixes:

Number of parameters

Include unlimited number of parameters in sketched profiles.


Sketch browser dialog box

Now you can view and modify sketch properties in the Sketch browser dialog box:

1. Click Sketch browser icon to open the Sketch browser dialog box.

• Click a line, dimension, chamfer or constraint in the Cross section sketch editor view and Tekla Structures highlights it in the browser. Or click a part in the browser to have Tekla Structures hightlight it in the view.

• Use the popup menu, for example, to add equations, copy names, copy values, or delete objects.

• Create links between the sketch parameter variables, created in the Variables dialog box, and sketch objects to create parametric profiles.

• The sketches are parameterized in the same way as the custom components. For more information, see Using variables to define cross section properties in the online help.

Objects included in the sketched profile.


Chamfers Use chamfers when sketching profiles:

1. In the Cross section sketch editor view, the yellow circles represent chamfers. Double-click a yellow circle to open the Chamfer properties dialog box:

2. Select chamfer type, enter X and Y dimensions.

3. Click Modify and the chamfer is applied to the selected corner.

The chamfers are shown in the Sketch browser dialog box, where you can add equations to them.


Extrude sketched polyline

You can now create easily a cold rolled (constant thickness) cross section by sketching an open polyline, and defining extrusion type and thickness of the pro-file.

Extrusion type defines how the polyline is extruded:

Sketch editor view Sketch browser dialog box

Description

Extrusion Type

Extrusion Type = 0

Polyline is extruded sym-metrically from the center line (the line you have sketched).

Default value

Extrusion Type = 1 Polyline extruded to the outside of the sketched line.

Extrusion Type = 2 Polyline extruded to the inside of the sketched line.


Use equations in Thickness property to define the thickness of the extruded polyline.

Angle constraint Add angle constraint to a sketch:

1. Click icon in the Cross section sketch editor view.

2. Pick the lines counter-clockwise.

3. Tekla Structures creates the angle constraint.

Visualization of constraints

Now you can view the constraints in the editor view, by selecting them in the Sketch browser dialog box:

1. Click Sketch browser icon .

2. Select the constraint in the Sketch browser dialog box.

3. The line in question is displayed as dashed line, and the constraints are high-lighted in the Cross section sketch editor view.


Deleting constraints

To delete a constraint:

1. Click Sketch browser icon .

2. Select the constraint in the Sketch browser dialog box.

3. Right-click and select Delete in the popup menu:

Part and connection positioning planes

Use commands Show or hide part positioning planes and Show or hide connection positioning planes on the sketching toolbar to view the control positioning planes of the profile.

Connection positioning planes

Tekla Structures uses the connection positioning planes for positioning compo-nents to parts, for example, custom components to concrete slabs, if you have selected the Position in relation to primary parts checkbox in the component dialog box, on the General tab.

By default, Tekla Structures uses solid edge planes of the main part as the refer-ence points, but if you have modified the part or connection positioning plane in Cross section sketch editor view, Tekla Structures uses those instead of the default planes.

Part positioning planes

Part positioning planes (top, bottom, left and right) affect how the part is posi-tioned in the model (the properties on the Position tab, in the part properties dia-log box).


The following pictures display the default part positioning planes in the Cross section sketch editor view and in part end view.

The following images display modified part positioning planes in the Cross sec-tion sketch editor view and how the part reference line position has changed in the model:

Cross section sketch editor view: Part positioning planes in the default position

Part end view: The On plane and At depth properties are both set to Middle, with 0 offset.

Cross section sketch editor view: Modified part positioning planes.

Part end view: The On plane and At depth properties are both set to Mid-dle, with 0 offset.


To view or modify the planes:

1. Open the Cross section sketch editor view.

2. Click icon to show default part positioning planes, or icon to show the connection positioning planes.

• The part positioning planes are displayed as blue lines. • The connection positioning planes are displayed as green lines.

3. In the upper right and lower left corners are handles which you can drag to modify the location of the planes. The modified planes are saved with the sketch.

4. To revert to the default planes: select the plane lines and select Delete from the pop-up menu. Then click the Show or hide part positioning planes or Show or hide connection positioning planes icon again.

Miscellaneous fixes

• Sometimes the profile dimensions were corrupted when the sketched profiles were updated in the model after closing the sketch editor. Fixed.

For more information on sketching tools, see Sketching and using cross sec-tions in the online help.


Units in parametric profile nameThe parametric profile name now consists of correct imperial units and values:


Binding objects to center and cut planesTekla Structures 11.1 includes new options for binding objects to planes:

• Center planes

• Cut planes • Use to bind object handles to cut surfaces.

When you create distances to bind model objects together, use the second list box on the Snap settings toolbar to select the plane to bind the object to. The options are:

• Boundary planes of parts • Center planes of parts• Outline planes of parts • Cut planes• Grid planes

Create clip planesNow you can create up to six clip planes to any rendered model view:


To create a clip plane:

1. Select a rendered model view

2. Right-click and select Create clip plane from the popup menu.

3. Select the clip plane position: pick any plane.

4. To end the command, right-click and select Interrupt.

5. Clip plane is displayed with a symbol.

Selected plane Clip plane symbol


6. To move the clip plane, click the symbol, drag and drop it to the new loca-tion.

You can only move the plane to the direction of plane normal (and opposite).

7. To delete a clip plane: Click the clip plane symbol and click Delete.

MiscellaneousTekla Structures 11.1 includes following new features and fixes:

Plane-line and part-line intersection points

• Command Points > Plane-line intersection did not work cor-rectly. Now once you have picked the plane, you can pick multiple lines after that.

• Command Points > Part-line intersection did not work cor-rectly. Now once you have picked the part, you can pick multiple lines after that.

• For more information, see Points > Plane-line intersection in the online help.

Part cutsIf a part was cut with part cut or polygon cut command, using this part to cut another part did not work correctly. Fixed.


Numbering partsEven if a plate created as beam and a contour plate were identical, they got dif-ferent position numbers. Now Tekla Structures assigns same position numbers to plates created as beams, and to contour plates.

Handle sizeNow you can modify the handle size in the model view:

1. Open the Advanced options dialog box (Tools > Advanced options...) and go to Model view category.

2. Define the handle size with variable XS_HANDLE_SCALE.

• The default value is 1.0 • Value larger than 1.0 enlarges the handles • Value smaller than 1.0 decreases the handle size

3. Close the rendered view and reopen it to view the modified handle size.

Miscelleneous fixes

• When you saved a model in the multiuser mode, the work plane sym-bol was sometimes drawn to wrong position. Fixed.

1.3 DrawingsThis section describes the following new features and fixes:

Cloning from template Now you can clone drawings from templates. Templates are drawings included in a Tekla Structures model, which is defined as the template library.

• To define the drawing template library, set, in the batch file, the vari-able XS_DRAWING_TEMPLATES_LIBRARY to point to the model folder that contains the template drawings:

set XS_DRAWING_TEMPLATES_LIBRARY=%XS_RUNPATH%\DrawingLi-brary

• For example:

set XS_DRAWING_TEMPLATES_LIBRARY=C:\TeklaStructuresMod-els\CloningTemplate (where CloningTemplate is the model name).


To clone from a drawing template:

1. Create the template drawings, and define the template library in the batch file.

2. Click Drawing > Clone drawing... (or click Clone... in the drawing list dialog box), to open the Drawing cloning dialog box.

3. Select the drawing objects that you want to copy into the new drawing, in the Objects and actions in cloning properties.

4. Select Drawing template option and press Templates... button.

5. In the Drawing templates dialog box, select the template drawing.

6. In the model, select the part.

7. In the Drawing cloning dialog box, click Clone selected.


Hatch patterns for surface treatment Now you can use hatches with all surface treatment types in drawings.

To show hatching in the drawing, select Show pattern checkbox in the drawing surfacing properties dialog box:

The direction of the hatch pattern is the same as the direction of the surface treat-ment.

Surfacing.htc Which hatch to use with which surfacing type is configured in surfacing.htc file (located in .../environments/*your environment*/system folder).

In the file is defined following:

• Surfacing type:• 1 = concrete finish• 2 = special mix• 3 = tile surface• 4 = steel finish

• Surfacing code:• This is the abbreviation used in drawings and reports, for exam-

ple, MF.• See product_finishes.dat file for a full list of surfacing codes.


• Hatch name

• Extra scale• Extra scale is a numeric value that Tekla Structures uses to scale

hatches.

• Color (optional)• If you do not define a color for a hatch in the surfacing.htc

schema file, Tekla Structures uses the color defined on the Appearance tab of the drawing surfacing properties dialog box. The color and type definition in Visible lines is used for the front side surface treatment, and in the Hidden lines for back side.

View available hatches

To view a list of existing hatches:

1. Open, for example, Circle properties dialog box by double-clicking Circle icon on the Drawings: Drawing toolbar. (Also other drawing object properties include fill type selection).

2. Click Select... to open the collection of available hatch patterns. When you click a pattern, you can view the name in the Type list box, in the Circle.

Associative drawings Tekla Structures 11.1 includes following improvements in associative drawings:

Texts in drawings Text objects are now associative (text position is updated when the model changes).

Text type DescriptionText The insertion point (the point you pick

when adding the text) is associative. You can drag the text, and it stays associative.

Text along line The start and end point of the line are asso-ciative.

Text with leader line The starting point of the leader line is asso-ciative.

The direction angle is maintained when the model changes and drawings are updated.

Along line, arrow at start point

The starting point of the line is associative (the point where Tekla Structures creates the arrow).


Drawing objects The following drawing objects are now associative:

Associative notes Tekla Structures 11.1 includes new drawing object: associative note, you can use associative note as an extra marks in drawings. The note works like, for example, part mark, and it is updated according to the changes made to the object it is added to.

Associative note can be added to following objects:

• Part• Bolt• Reinforcing bar• Surfacing

Object Icon DescriptionLine One or two points (start and end points) can be

associative.

Arc

Circle The center point is associative.

Rectangle The first two points are associative.

Polyline One or two points (the first two) can be associa-tive.

Polygon

Cloud

Command IconAssociative note with leader line

Associative note without leader line.

Associative note along line.


You can add multiple notes to one object, and place the notes freely. Add and modify the content of the notes the same way as with part marks.

Associative notes can contain following elements:

To add associative note, click Create > Associative note and select type:

With leader line and Without leader line options:

Field name Description


Primary and secondary parts in templatesYou can now add attributes of primary and secondary parts of connections in templates and reports:

• The row content type is CONNECTION.

• Value field formula can be GetValue("PRIMARY.XXX") or GetValue("SECONDARY_1.XXX"), for example, GetValue("PRIMARY.AREA").

Surface treatment in templates and reports• In previous version template attributes SURFACING_NAME and

CODE gave the same result. Fixed.


• New template attributes in Tekla Structures 11.1: MATERIAL, NAME, and THICKNESS for surface treatment.

See the following example on corresponding properties and template fields:

Show or hide +0.000 levels• The template attributes ASSEMBLY_BOTTOM_LEVEL,

ASSEMBLY_TOP_LEVEL,CAST_UNIT_TOP_LEVEL, CAST_UNIT_BOTTOM_LEVEL return nothing in the part marks, if the level value is zero (+0.000).

• If you need to see also the zero values, click Tools > Advanced options, then in the Marking: parts category, set the new variable XS_DRAWING_IGNORE_ZERO_LEVELS_IN_PART_MARKS to FALSE.

• By default this variable is set to TRUE, which means that zero levels are not shown in part marks.

Fixes• In the Template Editor, text fields were too long with some font sizes

in japanese text. This problem has now been fixed.

• Template attributes DATE and TIME are now available for all rows.

• The move command now has a predefined shortcut m.

NAME

CODE SURFACING_NAME

MATERIAL

THICKNESS


• The template attribute NAME_SHORT now returns correct values from the bolt assembly catalog:

• for bolts, it returns bolt "Standard"• for studs, it returns the name of the bolt, not the short name of

the bolt asssembly.

Plotting and printingTekla Structures 11.1 includes following new features and fixes:

Plotting gray hatchesNow you can define a special hatch color, which will not be converted to black when plotting. This color will be plotted as color or grayscale, depending on the selected printer settings. The hatch color is defined using the RGB (Red Green Blue) values (scale is from 0 to 255).

To define a special color hatch:

1. Open the Advanced options dialog box (Tools > Advanced options...) and go to Hatching category.

2. Define the gray color with the following variables:

set XS_HATCH_SPECIAL_COLOR_R to 214

set XS_HATCH_SPECIAL_COLOR_G to 214

set XS_HATCH_SPECIAL_COLOR_B to 214

The default value for hatch is black (0,0,0).

Smaller values give darker shade, higher values lighter.


You do not have to restart Tekla Structures to activate changes to these vari-ables.

To use the hatch color:

1. Open the drawing.

2. Open the drawing object properties dialog box (rectangle, polygon, or cir-cle).

3. Select fill color Special.

The hatch is plotted in color or grayscale, depending on the selected printer settings.


To use the same color in automatic section hatching, set the color index number in the .htc file to 120.

For more information, see Hatching in section views in the online help.

Plotting continuous lines To display continuous lines (for example, if the line goes through text or drawing marks) in plotted drawings or in printing to DXF / DWG, switch the following variables off:

• XS_USE_LINECLIP_IN_EXPORT for DXF / DWG export.

• XS_USE_LINECLIP for normal plotting.

To display continuous lines:

1. Click Tools > Advanced options, and go to the Plotting category.

2. Type in FALSE in the Value field of the variable.

• By default, the value is TRUE.

In print the gray shade is darker.



Miscellaneous• You can now set the variables XS_PLOT_ORIGIN_MOVE_X and

XS_PLOT_ORIGIN_MOVE_Y in the Advanced options dialog box, Plotting category, without restarting Tekla Structures.

Section view direction Now Tekla Structures creates the section views in GA drawings always so, that the z axis points up:

• Section views for XY plane views, or gently sloped planes like roof planes, the viewpoint is rotated so that section view’s vertical axis will be parallel to the global z axis.

• In section views for XZ or YZ planes, the z axis points up.

Confirm save when closing a drawingIf you have not made any modifications and close the drawing, Tekla Structures does not display a confirmation dialog to prompt you to save the drawing.

Use variable XS_ALWAYS_CONFIRM_SAVE_WHEN_CLOSING_DRAWING to set Tekla Structures always display the confirmation dialog:

1. Click Tools > Advanced options... and go to the Drawing properties category.

2. Set XS_ALWAYS_CONFIRM_SAVE_WHEN_CLOSING_DRAWING to TRUE.

• The default value is FALSE.

XS_USE_LINECLIP = TRUE XS_USE_LINECLIP = FALSE


Extra line around hatchingNow you can add extra lines, in different colors, around the automatic hatching in section views. To set Tekla Structures add extra lines:

1. Click Tools > Advanced options... to open the Advanced options dialog box.

2. In the Hatching category, select variable XS_SECTION_LINE_COLOR.

3. Enter value for the color (from 1 to 14) in the Value field.

• The default value is 0 (no extra lines).

• The number corresponds to the color sequence in drawing object properties:

MiscellaneousTekla Structures 11.1 includes fixes for the following:

Parts • Round holes were shown as rectangular, if the part representation was set to Bounding box or Base box.

Main part direction

• Problems occured with complex main part handling. Main part direc-tion was handled in a wrong coordinate system.

To show lines around hatching, and to be able to add extra lines in different colors, you may need to set variable XS_DRAW_ALL_SECTION_EDGES_IN_DRAWINGS to TRUE in the batch files. The variable is set to FALSE by default.

0123456etc.


Drawing views • If the associativity was set (variable XS_INTELLIGENT_DRAWING_ALLOWED set) and you dragged the drawing view frames to change their size, froze the drawing and opened the drawing again, the drawing view frames took the original size. Fixed.

Marks • Surfacing mark properties: Leader line type settings did not work correctly.

• If a drawing included several level marks, only one was updated when the model was changed and you updated the drawing. Now all the level marks are updated.

• Part mark properties now include Finish in the elements list. Use this element in mark to show the Finish property of the part.

• When in general arrangement drawings, the Parts out of view plane property is set to Not visible (in General - part mark properties dialog box, on the General tab), you could not add part marks to parts out of the view plane. Now part marks can be created regardless of the visi-bility settings.

Dimensioning • Sometimes grid dimensions were overlapping in drawings. Now grid dimensions are always freeplaced.

• In Tekla Structures 11.1, Combine equal dimensions property cannot be used with US absolute and US absolute 2 dimension types.

• Degree symbol in angle dimensions is now closer to the text:

• Sometimes complex main parts were not dimensioned correctly, when variable XS_COMPLEX_PART_MEMBERS_DO_NOT_HAVE_TO_BE_MAIN_PART was set (Tools > Advanced options..., Dimensioning: parts category) and the first (the lowest or leftmost) part was secondary.

• Sometimes protection did not work correctly with dimension line exten-sions. Now the extension line protection areas are created correctly. For more information on protection areas, see Protection in the online help.

• If you modified the second or the second last dimension point in a combined dimension line, also the tag texts were deleted from that side of the dimension line. Fixed.

Grids • Sometimes you could not drag the grid line mark, if there was only one grid line in the drawing. Fixed.


Texts and symbols

• The Angle property in the Text properties dialog box affected how the protect area of text with leader line was drawn. Now also the protect area of text with leader line is always drawn horizontally.

• Sometimes when you moved or copied texts in drawings, using the pop-up menu commands, Tekla Structures freeplaced them. Now only texts that have Placing property set to Free, are freeplaced, and texts with fixed placing are moved or copied where you want to place them.

• Symbols were not placed correctly when picking the insertion point in the Drawing editor. Fixed.

• Multinumber characters were not always correct in single drawings, if the number of valid characters was different for assembly and part multinumbers (set with variables XS_VALID_CHARS_FOR_ASSEMBLY_MULTI_NUMBERS and XS_VALID_CHARS_FOR_PART_MULTI_NUMBERS). Fixed.

Keyplan • Using key plan reserved a lot of memory. Fixed.

Saving, opening and closing

• If you froze a drawing with P flag, and updated it afterwards, Tekla Structures displayed a warning message saying the drawing is not up to date. Fixed.

• Drawings created with old Xsteel versions (version 5.5 or older) could not be opened in Tekla Structures. Fixed.When you used user-defined attributes in the value field of variable XS_ASSEMBLY_POSITION_NUMBER_FORMAT_STRING (Tools > Advanced options..., Numbering category) opening drawings was slower than without it. Fixed.

Cloning • If a drawing represents several similar assemblies and one of the assemblies is modified, a new assembly drawing is cloned automati-cally to suit the changed situation. The cloning did not always work properly in 11.0 or earlier versions, if the single part views were pre-sented in the assembly drawing. The single part views are still not cloned when cloning assembly drawings.

Drawing list • Sometimes the Title fields in the drawing list were displayed incor-rectly when creating drawings. Fixed.


1.4 Import and exportThis section describes the following new features and fixes:

3D DWG/DXF exportIt's now possible to export Tekla Structures model as 3D DWG.

1. Open a Tekla Structures model.

2. Click File > Export > 3D DWG... to open the Export 3D DWG/DXF dialog box.

• This dialog box has replaced the Export 3D DXF dialog box. Now you can use the same properties to both DWG and DXF export.

3. Modify the properties:

• Export as: You can export the model as faces, lines or reference lines.

• Part and Bolt accuracy: Normal, High or No bolts.

• Cuts: to export cuts

• Inner contours: for example, to export the inner contours of a tube. If you select No, the tube is exported as a solid.

4. Enter the file name, or use Browse... to navigate to another file

5. Select whether to export as DWG or as DXF.


6. To export the model, click:

• Export all to export the whole model, or • Export selected to export selected parts from the model.


• Reference import now supports layers in DWG, DGN, and IFC files.

• In Tekla Structures 11.0, when you copied objects from another model (Edit > Copy from model...), all phases were imported into the current phase. Fixed.

• If you tried to turn on the visibility of an IFC reference object while the IFC file was not in the right location, Tekla Structures closed without any warning.

1.5 Custom componentsThis section describes the following new features and fixes:

Performance improvementsNow custom component creation in large model is even ten times faster than in previous versions.

Exporting 3D DWG or DXF as Faces uses more memory and might take time, but the end result is better.

If the model is large, or you have less memory to use, Export as Reference lines option is faster, and the resulting file size is smaller.


Automatic seam positioningCustom seams include new feature: automatic positioning.

You can now select whether to place the seam to the points you picked, or to let Tekla Structures place the seam automatically.

Using Excel with custom componentsNow you can link Excel spreadsheets with Tekla Structures custom components, for example, for connection check.

For custom components, you need to add property Use external design to the cus-tom component dialog box. Otherwise use Excel with custom components the same way as with other components.

To add Use external design property to the component dialog box:

1. Select the component, then right-click and select Edit custom component.

2. In the custom component editor, click to open Variables dialog box.

3. Click Add button, and enter following information:

To place the seam to the posi-tion you picked, select Place to picked positions checkbox.

To place the seam automatically, deselect the Place to picked positions checkbox, and select one of the positioning options.


4. Save and close the custom component editor.

5. The new property Use external design is now in the component properties dialog box.

Spreadsheet location

By default, the spreadsheets locate in folder ..\TeklaStructures\*your version*\environments\country_independent\exceldesign.

• The location of the spreadsheet is specified in excel.vb tile (in ..\TeklaStructures\*your version*\nt\bin\plugins folder).

Spreadsheet name

The name of the file must be component_*component name*.xls

• For example component_custom1.xls for a custom compo-nent named custom1.

For more information on the required Excel files, file locations and how to per-form the connection check with Excel, see Using Excel in connection design in the online help.

Imperial units in formulasTo convert Imperial units to internal units (metric) in formulas, use the new func-tion ValueWithUnit(value, unit) or acronym vwu(value, unit). Example: vwu(4.0, "in") returns 101.6 mm

Known units are:

• "ft" ("feet", "foot")• "in" ("inch", "inches")• "m"• "cm"• "mm"• "rad"• "deg"

Battering connection (13) improvementsNow if you fit the secondary part at an angle to the main part, and the battering would be less than the value you entered in the angle field, the free space is adjusted so that the final length of the secondary beam is the same as the length of the corresponding horizontal beam.



• Part cuts could not be used to cut parts in the Custom component edi-tor. Fixed.


1.6 ComponentsThis section describes the following new features and fixes:

Stairwell and elevator shafts (90)Tekla Structures 11.1 includes new macro, for creating stairwells and elevator shafts:



• In previous versions you could not modify a component, created in Tekla Structures Steel Detailing configuration, in Tekla Structures Full Detailing configuration without converting it.

Now you can modify components created with other configurations in the Full Detailing configuration, without converting them, if the component does not include reinforcing bars or cast units welds.


2 Tekla Structures 11.1 Steel Detailing

Release Notes 53Tekla Structures 11.1 Steel Detailing


Contour plate orientationInstead of automatic plate orientation, you can now set the contour plate main axis to follow the line created by the first and second points you pick. Use this feature if you want to have different plate orientation in drawings or reports.

To define the contour plate orientation with first and second picked points:

1. Create the contour plate. The first and second picked points will define the plate’s main axis.

2. Double-click the plate to open the Contour plate properties dialog box.

3. Click User-defined attributes..., and go to the Orientation tab.

4. Select From 1st to 2nd creation point in the Main axis direction list box.

5. Click Modify, and close the dialog box.

6. Click Tools > Numbering > Modified to update numbering.

7. Create, for example, a single-part drawing of the plate, to view the orienta-tion of the plate.

4. Click the Browse button against the Input file field to locate the file to import.

5. Click OK to import status information into the model.

CNC• In Tekla Structures 11.1 you can include hard stamps also for second-

ary parts in DSTV files. To do this, enter TRUE in the Value field for the variable XS_SECONDARY_PART_HARDSTAMP.

Note that Tekla Structures does not create hard stamps for plates.

• In Tekla Structures 11.0 DSTV format was fixed to follow the DSTV standard even better than before, by switching the places of phase and drawing identification in the DSTV file header. Because of this change, dstv2dxf converter does not add correct texts to DXF files, and some CNC controller softwares interprets the DSTV files incorrectly. To enable the fix and create similar DSTV files as before, set variable XS_NC_DISABLE_PIECE_IDENTIFICATION_FIX to FALSE in the batch files. By default, the variable is set to TRUE.

• In Tekla Structures 11.0 you could not create NC files of, for exam-ple, z or zz profiles. Now you can create NC files of all other profiles by using profile type SO in NC file settings dialog box.

• In Tekla Structures 11.0 hard stamps did not affect the DSTV file names. This has been fixed. Now the file name is based on Assembly position and / or Part position elements (on the Hard stamp tab, in the NC file settings dialog box).

IFC importThe reading of boundary representation (BREP) in IFC reference files has been improved.



Building (S91)Use this macro to create a portal frame building with saddle roof. The macro cre-ates frames and connections, purlins, roof and vertical bracing, and gable end posts. You can use Tekla Structures system connections and custom connections in the macro. The left and right columns and rafter profiles are identical.

To create a building with the macro:

1. Click Ctrl + F to open the Component catalog, and search for Building (S91) macro.

2. Double-click the macro to open Building (S91) dialog box.

3. Modify the properties, and click Apply or OK.

4. Pick the creation point for the building. The building will be created in X and Y direction from the picked point, in the current work plane.


Beam to beam connectionsTekla Structures 11.1 includes the following new features and fixes:

Two sided clip angle (143)• Now contains the Angle Box tab which used to add a seat angle under

one of the secondary parts to fulfill OSHA safety requirements.

Use the options on this tab to determine seat angle position, orientation and method of attachment (bolted or welded). Use the options on the BoxPBolts and BoxSBolts to control the bolting of the seat angle to primary and second-ary parts.

Shear plate simple (146)There is no longer a gap between shear plate and column with NS / FS options.


Beam to column connections Tekla Structures 11.1 includes the following new features and fixes:

Haunch (40)Entering a value on the Picture tab for a gap between the column and the end plate now correctly affects only the distance between the column and the end plate, not the plate on the web of the column.

Column with stiffeners W (182)Now uses the correct properties for weld no 2.

Bracing connections Tekla Structures 11.1 includes the following new features and fixes:

Turnbuckle bracing (S3) Turnbuckle was rotated incorrectly when created between columns. Fixed.

Windbracing (1)Connection Windbracing (1) did not work in Tekla Structures 11.0. Fixed.

Macros and detailsTekla Structures 11.1 includes the following new features and fixes:


UltraZED File transfer (93) UltraZed file transfer (93) macro did not process Apex Struts (ULT-ATC* sec-tions). Fixed.

Multiple stiffeners (1064)Chamfers were created in the wrong corner in Tekla Structures 11.0. Fixed. When the primary part is C-profile, the chamfers are incorrect.

MiscellaneousTekla Structures includes following new features and fixes:

• Component Std bracing connection (67) created the second bolt incor-rectly, and the plates were not bolted together. Fixed.

• Component L spice (175) did not handle the chamfers correctly. Fixed.

• You can warp, camber and shorten steel and concrete beams and col-umns.

• Seams and connections work with warping.

Miscellaneous• Now when you copy cast unit members and reinforcing bars, the new

object will belong to the same assembly if the copied object is inside an existing assembly.


Dimensioning by reference pointsIn previous Tekla Structures versions cast-in embeds (steel parts or assemblies added to cast units) were dimensioned in cast unit drawings the same way as sec-ondary objects in assembly drawings. In Tekla Structures 11.1 the embedded objects can be dimensioned by reference point.

To set dimensioning by reference points:

1. Open the Cast unit drawing properties dialog box and click Dimensioning...

2. On the Position dimensions tab in the Cast unit - dimensioning properties dia-log box, select By reference point in the Embedded objects list box:

Custom components in cast-unitsAdding custom components, used for example as cast-in embeds, to cast units is now made easier:

• Now you can add the whole custom connection to the cast unit by right-clicking and selecting Cast unit > Add to from the pop-up menu:

• You can also remove the custom component from the cast unit, and explode the cast unit from the pop-up menu.


Modeling of floor bay (66)Use this new component to create various types of concrete slabs. The compo-nent creates slabs between two support lines, which can be polylines or sloped.


Concrete stairs (7)Includes the following new features and fixes:

• User interface includes pictures.

• New properties: you can define thickness of stairs in top and bottom and the draft.


The concrete stairs (7) macro has now default values: properties which are empty use the default values.

Modeling of slab area (88)Tekla Structures 11.1 includes fixes for the following:

• When you selected Seam center point in the Origin point list box, the slabs were not positioned correctly, and a gap might have been cre-ated between the slabs.

• In some cases the macro created steel beams instead of concrete. Fixed.

• Tekla Structures did not always update default values, if you entered a new value, and then erased value field and clicked Modify. Fixed.

• Now the created slab can rotate only around its center axis.

• You can now warp slabs with fanned layout.

• Tekla Structures no longer ignores the standard spacing value of seams, when the option Width of indexed element is used.



• It is now possible to add equations to strand properties in the model browser.

• Xsnap now also works for seam handle points.

• Cutting hollow core slab with Grating penetration (92) macro gener-ated an application error. Fixed.

Component Description


4 Tekla Structures 11.1 Analysis and design

4.1 Analysis and designThe Tekla Structures 11.1 Analysis and Design module contains the following new features and fixes:

• Loading (p. 74)• Slab spanning direction (p. 75)• Analysis & Design models dialog box (p. 76)• Response spectrum (p. 76)• Analysis properties for slab components (p. 77)• Connections of plate elements improved (p. 78)• Rigid diaphragm improvements (p. 78)• Miscellaneous (p. 79)

Release Notes 73Tekla Structures 11.1 Analysis and design

LoadingTekla Structures includes new part properties to be used with area load genera-tion according to part geometry. The Loading tab has been added to the beam, polybeam, concrete beam, and concrete panel properties dialog boxes. This fea-ture is especially needed for concrete slabs, which are not always included in the analysis model.

Generate self weight load includes part’s, for example deck’s, weight to analysis model as a load even if the part is not otherwise included in the analysis model. If part is included in the analysis model, self weight is not generated as a separate load.

You can also enter slab live load or additional self weight (screed, services) using three additional loads with load group name and load value. The direction of the load is according to load group direction.

Using Part names filter you can make sure that area load from concrete slab is transferred to correct parts, for example beams supporting the slab. So you usu-ally enter the beam name as a value.

74 Release NotesTekla Structures 11.1 Analysis and design

Select Use continuous structure load distribution if you want to divide the most of the load to middle supports on continuous structures.

Slab spanning directionWith new spanning settings of the slab you can better control how slab is con-nected to beams and which beams carry the load from slab.

Spanning has following options:

• Single spanning slabs carry load in one direction. Beams parallel to single spanning direction will not be connected to the slab, and will not carry the load from slab.

• Double spanning slabs carry load in two directions. Beams in both directions will carry the load.


You can define primary axis direction with following optional ways:

• Click Parallel to part and then select the beam in the model that is parallel to the direction.

• Click Perpendicular to part and then select the beam in the model that is perpendicular to the direction.

When load is applied on slab, the spanning setting of the load does not have any effect, but the spanning is determined using the spanning setting of the slab itself.

Analysis & Design models dialog boxCommand Analysis > Create model is now in the Analysis & Design models dia-log box too.

Analysis menu commands are now available from the pop-up menu in the Anal-ysis & Design models dialog box.

Response spectrumSeismic analysis using response spectrum is now available in Analysis model attributes. The spectrum data, loads and masses will be sent to STAAD.Pro for analysis. You can either use displacement or acceleration spectum. Damping is specified as modal damping.

Like in UBC seismic analysis, seismic load groups (X and Y) are created auto-matically.

Member and point loads are analysed according to the specified seicmic masses.


Analysis properties for slab componentsYou can now set analysis and load properties for parts created by slab compo-nents:

• Slab generation with polygon plate (61) • Slab generation with points (62)


Connections of plate elements improvedSlab/wall connectivity in the analysis model is now more flexible. In versions 10.2.x and 11.0, walls were not always connected to columns and beams auto-matically, but you needed to use node offsets (user-defined attributes) to move the wall in analysis model.

In Tekla Structures 11.1 you just select the Extended clash check checkbox in the Analysis model attributes dialog box and if slab or wall clashes with beams, col-umns, or other slabs or walls they will be connected in the analysis model, using rigid links if necessary.

Slab spanning also affect slab/beam connectivity automatically. See Slab span-ning direction (p. 75).

Rigid diaphragm improvementsAdjacent rigid diaphragms are now merged. In previous versions floor consist-ing of several precast slabs did not work correctly as a rigid diaphragm when each slab was defined as a rigid diaphgram.

A filter is defined for rigid diaphrgam. Only nodes which belong to a part match-ing the filter will be connected. You can use for example column_filter to connect only column nodes with rigid diaphragms.

Slab components Automatic rigid diaphragm has also been added to the following components:

• Slab generation with polygon plate (61) • Slab generation with points (62)

To connect column nodes using rigid diaphragms,

1. Set Analysis type to Rigid diaphragm.

2. Type "column_filter" in the Filter field.



User-defined attribute Truss_member removedAttribute truss_member is no longer in use.

For old models, truss macros have to be executed to set analysis type "truss" for vertical and diagonal parts.

Warning and error messagesTekla Structures now displays a warning or an error message each time errors occur in the analysis.

Too dense element mesh Very dense element mesh was generated for slabs if the slab was created to cor-ner of column, so that in the analysis model slab extended over the analyse line of column as a cantilever.


The default cantilever length is now set to 300 mm, cantilevers shorter than this will be removed from the anlaysis model.

You can change the limit with the following user-defined attribute:

attribute("AD_plate_min_cant", "j_AD_plate_min_cant", dimen-sion,"%.3f", no, none, "0.0", "0.0")

{

value("", 0)

}

Fixes• Now parts created by slab and truss components will be added to full

analysis model automatically.

• Tekla Structures now displays a warning in the analysis log file, if there are no members, supports, or loads in the analysis model.

• Unnecessary triangles are no longer created for wall panel. When a beam was connected to a wall and the beam was slightly out of place because of a modeling error, wall mesh could be disrupted. Some tol-erance is now allowed.


• Beam longitudinal offsets (dx) resulted in duplicate analysis mem-bers in some cases. A new user-defined attribute Consider longitudi-nal model offsets has been added, to control how beam offsets are handled. The options are:

• Auto (default) Dx offset is taken into account if it extends the beam or if it shortens the beam, and there is a node near the shortened position.

• None • Extending only This is the old functionality, which takes dx off-

set into account when it extends the member and ignores it when it shortens the member.

• Always

• The variable XS_AD_NODE_COLLISION_CHECK_DISTANCE now works with Extended clash check.

• When merging outline nodes of connected walls or slabs, orphan nodes remained in the model. These caused warnings in the analysis, but they were not harmful otherwise. These nodes are now removed.

• The Element type (triangular/quadrilateral) list box has been removed from the Slab and Panel properties, because quadrilateral option does not work yet.

• In the previous version saving the Analysis load modeling... properties failed.

• Loads did not keep their phase when copying, they all went to the current phase. Now the copied loads keep their original phase.

• To prevent strange node/element positions, Tekla Structures now checks the angle difference between analyse and physical members. If the angle difference exceeds the limit, a warning message is shown. To highlight the member in the model, open the log file and click the warning row. The default warning limit is 10 degrees. You can change the limit in the Setup > Advanced options.

• The load distribution sometimes failed if a line or point load was applied to a polybeam consisting of more than three points. You could prevent this problem, if you used very large bounding box around the load. This problem in bounding box handling has been fixed.

• Tekla Structures generated an application error, if the analysis model contained over 50 load groups and load combinations dialog box was opened. This limit still exists, but the application error is prevented and a warning is displayed.


• Applying temperature load for the whole structure is now easier than in the previous versions. To create a temperature difference load for the whole structure, just insert one temperature load with Tempera-ture change for axial elongation, and make the bounding box big enough to contain all beams and columns of the structure.

• If analysis (longitudinal) member offset was 100 mm or less, but not zero, member loads were not transferred correctly to analysis model.

• The option Create fixed support conditions automatically in load prop-erties dialog boxes has been renamed to Use continuous structure load distribution.

• In Tekla Structures 11.0, if you had not run analysis in the session, using Get results command, or creating an utility report caused appli-cation error. Fixed.

• Load positions on plates did not always snap correctly to nearby plate nodes.

• Load distribution did not work correctly, if members with loads had overlapping nodes.

• When you modified a part, the user-defined attribute Design group (optimisation) (on Analysis tab in the part user-defined attributes dia-log box), was incorrectly cleared. Fixed.

Miscellaneous (p. 90)

Batch file settings in the user interfaceIn Tekla Structures 11.0 we refer to environment variables simply as variables.

To make it easier to manage batch file settings, the variables can now be used in a new dialog box. To view or change variable settings, click Tools > Advanced options... to open the Advanced options dialog box. Variables are grouped together in categories. The left pane in the dialog box displays the list of catego-ries. Click a category to view the variables it contains in the right pane:

• The right pane show the variable Name and the Value. Variables have a description and the default value is shown in the dialog box.


• When you change the value and click OK, a warning message is dis-played if you need to restart Tekla Structures. If you do not get any warning message, it is not necessary to restart Tekla Structures.

• To get help for a variable, highlight it, then press the F1 key.

• All paths now support scandinavian characters (å, ä, ö).

You can still edit variable settings by editing batch files using any text editor, as you could in previous versions.

Any changes you make in the Advanced options dialog box overwrite changes you make by manually editing batch files. (For more information on the files the changes you make in the Advanced options dialog box affect, see the image below.)

We recommend that you use one method to set variables, not both.


Batch files are located in the following folders:

Performance improvementsTekla Structures 11.0 includes following improvements:

• Use more virtual memory, up to:• 3 Gb in Windows XP started with /3GB switch.

The /3GB switch increases the size of the virtual memory to 3 GB and restricts the kernel mode components to the remaining upper 1 GB. For more information, see Microsoft WHDC web page:

http://www.microsoft.com/whdc/system/platform/server/PAE/PAE-mem.mspx .

• 4 Gb in x64 systems with 64 bit Windows XP / 2003.• Empty string attributes (attributes that only contain a space " " or

nothing "") no longer increase the size of the database. Tekla Struc-tures now deletes empty string attributes when opening a single-user database, or converting a multiuser database.

• Modifying a view in models that contained DWG reference files used a lot of memory. This was because the DWG files contain triangular faces defined using four points. This is fixed. Tekla Structures now ignores the 4th point, which is the same as the 1st point. The refer-ence files are also correctly read and displayed.

• Deleting parts from very complex assemblies is now faster..

New Template Editor - version 3.2Tekla Structures 11.0 includes a new version of the Template Editor, version 3.2. It also includes the older version, 2.2. You can use templates and reports created with either of these Template Editors in Tekla Structures 11.0. You must convert templates created with Template Editor 2.2 to the new format to open and edit them in Template Editor 3.2.

Which version to use?

• To make minor modifications to an existing template, use Template Editor 2.2.

• To make major changes, or to create a new template, use Template Editor 3.2.

When you open a version 2.2 template in Template Editor 3.2, it prompts you to either convert the template, or click Retain and open the template in the old edi-tor.

• Click Convert to convert the template and open it in Template Editor 3.2. You have to manually edit the template, before you can use it.

• Click Retain if you do not want to convert the template.


http://www.microsoft.com/whdc/system/platform/server/PAE/PAEmem.mspx

Starting Template Editor

To start Template Editor 3.2:

• In Tekla Structures, click Tools > Templates...

OR

• From the Windows Start menu, select All Programs > Tekla Structures 11.0 > Tools > Template Editor 3.2

To start Template Editor 2.2:

• From the Windows Start menu, select All Programs > Tekla Structures 11.0 > Tools > Template Editor 2.2

OR

• Open it in folder ..\nt\TplEd\2.2

What’s New in 3.2 Template Editor version 3.2 features an improved user interface.

It contains several new features, including:

• Open several templates at the same time.

• Create almost any number of rules.

• Hide rows. For example, create more compact templates by hiding rows that only collect information for the summary row.

• Use row content types to filter out data. Row content types define what type of data a row can contain.

• Sum any fields together, for example, WEIGHT for parts and WEIGHT_GROSS for plates can now be summed.


• Import AutoCad and MicroStation files into graphical templates. For example, import blocks to use as title block.You can define the scale of the inserted DWG file by a scale factor, by width and height or by the maximum size.

• Create templates to output content in several columns.

• Add user-defined attributes to templates and reports. Add hierarchies and comments to the user-defined attributes in the attribute tree in Template Editor. For more information, see User-defined attributes in templates in the online help.

• Convert Imperial units to system units (metric).

File location Tekla Structures searches for the new templates in the following locations, in the following order:

To modify the folders these variables point to, click Tools > Advanced options and select the File locations group.

• Variable XS_TEMPLATE_DIRECTORY_SYSTEM is used to set the path to the default environment-specific templates delivered with Tekla Structures.

Tekla Structures searches for version 2.2 templates in two locations, in XS_TEMPLATE_DIRECTORY and in the first folder containing templates:

• model• project• firm• system templates• systemOnce Tekla Structures finds a template in one of these folder, it stops searching.

Miscellaneous

Log fileThe log file now shows the object ID for objects with illegal chamfer parameters.

• To view the log file, click Tools > Display log file > Log file... The object ID is shown in the log file in line "Illegal parameters for chamfer: Object id: *id number*".

• To highlight the the incorrect object in the model, click the relevant line in the log file.

The log file now contains the file name and line number if there are errors or warnings about reading inp files (for example, objects.inp).

Inquire dialog• To copy text from the Inquire dialog box, select the text, right-click

and select Copy from the pop-up menu (or press Ctrl + c).

• If you resize the Inquire dialog box to text automatically wraps.

• Using the Inquire bolts now displays the ID's of connected parts. The first ID is the first secondary part (the part with which the bolt is listed in reports), followed by the remaining secondary parts, an arrow and the primary part. For example: Connected part ID numbers: 256, 325 -> 178

GUID• Occasionally, some objects had incorrect globally unique ID’s

(GUID). Tekla Structures 11.0 assigns new GUID’s to these objects, which means the old incorrect GUIDs are no longer valid. If 11.0 you have exported the objects, then try to re-import them, you may have problems.

If text- or graphics-based templates display incorrectly in Tem-plate Editor 3.2 (for example, texts overlap or aligning fields is difficult), ensure that your monitor’s DPI is set to Normal size (96dpi).

To set DPI, open the Windows Control Panel and select Display properties > Settings > Advanced > General > DPI setting.


Save as• Saving the model to a folder other than TeklaStructuresModels no

longer creates an empty subfolder in the autosave folder.

• The Save as command now also saves a copy of the Analysis sub-folder.

Numbering• Now the Part name checkbox in the Numbering setup dialog box also

affects the Tools > Compare command.

• The Components checkbox has been removed from the Numbering setup dialog box.

• Messages in the numbering log file about overlapping series are now more informative.

• Illegal chamfer warnings no longer give a warning beep.

UndoUsing the Undo command only removes the last center of gravity point created, not all of them.

Error messageThe error message SmartHeap Library MEM_BAD_POINTER. sometimes appeared when exiting Tekla Structures. This is due to a minor bug in the shw32.dll file contained in Microsoft Service Pack 2. This was fixed in later ver-sions of the Microsoft OS. For more information, go to http://www.micro-quill.com/kb/xpsp2.htm.

Check databaseThe check database now identifies illegal profiles, as shown below:

Selecting part handlesTekla Structures 11.0 gives you the option to only select part handles within a window selection:

Binding objects to different types of planeWhen you create distances to bind model objects together, use the second list box on the Snap settings toolbar to select the plane to bind the object to. The options are:

• Boundary planes of parts• Outline planes of parts• Grid planes

• Select the parts.

• Hold down the Alt key, and select the parts again by clicking and dragging the mouse from left to right to define a win-dow selec-tion.


You can only bind objects to grid planes in the Model Editor:

See also Plane types in the online help.

Making construction lines magneticWhen you make a line magnetic, the handles on the line move with the line. In Tekla Structures 11.0 you can make construction lines magnetic. This is useful, for example, when modeling facades. To make a construction line magnetic, open the Construction line properties dialog box and select the Magnetic check-box:

Current limitations

Construction circles cannot be magnetic.

For more information on construction lines, see Points > Construction line in the online help.

Grid plane


Improvements to copy and move tools• New check boxes in the Copy - translate and Move - Translate dialog boxes

make it easier to select the directions in which to copy and move objects:

• When you try to copy an object to its current position (i.e. the dX, dY, and dZ fields are set to zero), Tekla Structures 11.0 displays a warn-ing.

• Using the Clear button in the Copy - translate dialog box now also saves the values in the dialog box, so they apply to subsequent copy commands.

Surface treatmentTekla Structures 11.0 includes tools to create surface treatments for concrete and steel parts, for example, unpainted areas, fire proofing, special finishes, or tile patterns.

Surface treatments are visible in models and can be included in drawings and reports.

You can create surface treatment for entire part faces, or to a selected area:

Surface treatment added to a part face.

Surface treatment added to a selected area.


Add to part face To add surface treatment to the face of a part:

1. Double-click the Create face surfacing icon to define the properties of the

surface treatment in the Surfacing properties dialog box: :

The properties include:

• Name - used in drawing marks.

• Surfacing type and Surfacing name - used in reports and draw-ings.

• Color - color in rendered views.

2. Click Apply or OK to save the properties and close the dialog box.

3. Select the part face to apply the surface treatment to:

• Ensure you are in a rendered view.• Move the mouse cursor over a part, the faces that you can select

appear in blue.• Click a part face to select it.

4. When prompted, pick the origin and direction of the surface treatment.

5. Tekla Structures creates the surface treatment.


6. Repeat steps 4 and 5 to continue adding the surface treatment to part faces.

Add to selected area

Use the Create polygon surfacing tool to add surface treatment to a selected area, for example you can specify unpainted areas of steel when you need to bolt an endplate to an unpainted surface:

To add surface treatment to a polygonal area:

1. Double-click Create polygon surfacing icon to define the properties of the

surface treatment in the Surfacing properties dialog box:

2. Enter or modify the surface treatment properties to use.

3. Click Apply or Ok to save the properties and close the dialog box.

4. Select the part you add surface treatment to.

5. Pick points to indicate a polygonal area.

6. When prompted, pick the origin and direction of the surface treatment.

7. Tekla Structures creates the surface treatment.


Cut parts If you add surface treatment to a part face that has openings, Tekla Structures uses cut parts and cut planes to cut the surface treatment. Check that the cut part cuts through the entire surface treatment.

Use the chamfers on surface treatment corners to reshape and move the corners. You can also create cuts to add openings to surface treatments.

Surface treatment options

The Type and Surfacing name properties in the Surfacing properties dialog box, are defined in product_finishes.dat file, located in the ..environ-ments\*your_environment*\system folder.

To add surface treatments to the file, edit it using any text editor and save it in the Firm folder (indicated by the variable XS_FIRM).

The first section of the file defines the types of surface treatment available. Do not edit this section:

// Product finishes// -------------------------//// Type : Type of surfacing// 1 = concrete finish// 2 = special mix// 3 = tile surface// 4 = steel finish// Code : Abbreviation code used in drawings and reports// Name : This is the name used in reports


The remaining sections define the options for each surfacing type. This is where you add new options.

In the example above:

• 1 is the surface treatment type (concrete finish)• MF is the code for the surface treatment option• "Magnesium Float" is the full name of the surface treatment

option

See also Add surface treatment to parts (p. 149)

MiscellaneousFixes Tekla Structures 11.0 includes the following fixes:

Polygon plate orientationThe following changes have been made to polygon plate orientation:

• The plate is not oriented when created or modified. • The plate coordinate system is always from the first point picked to the sec-

ond point picked. • Plate orientation is now always recalculated before any output (draw-

ings, NC files, reports).

This might affect plates created with older versions as follows:

• NC file contour points might start from a different point.• Stick models make appear different.

Fixes• Xsnap now also works for user-defined plane reference points.

• Deselecting a bolt group now also deselects bolt group handles.

• Bolt group handles are now visible in rendered views, even if the bolt is only a hole. Hole group handles are now also correctly displayed.

• The order in which bolts are selected no longer gives different clash check results.

• Standard grid view settings are now automatically loaded when open-ing a model.

// =========================================// *** Concrete Finish// =========================================// WET FINISH// ----------1 MF "Magnesium Float"1 SMF "Smooth Magnesium Float"1 WT "Wet Trowel"


• Some welded assymmetrical profiles disappeared from rendered views when you changed the display properties in another view from fast to exact. Fixed.

• Incorrect snap between part reference line and geometry line is now disabled.

• The list of saved filters now updates correctly when you change a model.

• Picking a plane sometimes generated unneeded planes or used a lot of memory, for example, when binding a point to plane or creating sur-face treatments. Fixed.

• Occasional runtime errors during multiuser save occurred when model contained multidrawings. Fixed.

• The Load list box did not display saved properties when you double-clicked a reference object to open the Reference object properties dia-log box. Fixed.

Associative drawingsAll drawing types in Tekla Structures 11.0 are associative. This means that draw-ing objects are linked to model objects, so that most drawing objects automati-cally update if the model changes, but you do not lose manual changes made to drawings. All drawing types are associative, whether created manually or auto-matically.

Tekla Structures updates the following drawing objects to reflect changes in the model:

• Marks• Dimensions• Welds• Views• Section symbols

Tekla Structures keeps the following manual changes made to drawings:

• Base points of drawing objects, for example if you drag an object to a new location.

• Drawing object properties, for example color, font, and line type.

Associative symbol

In drawings, an anchor symbol indicates that an object is associative.

• The associative symbol is not plotted. • To toggle the associative symbol on and off, click Setup > Associative

symbol, or use the shortcut Shift + A.

Examples Here are some examples that show associative drawings before and after modify-ing the model:

To keep manual changes made to single-part, assembly, and cast-unit drawings, freeze the drawings.

It is not necessary to freeze general arrangement or multidraw-ings, they are always associative.

If you add manual dimensions to a drawing that includes hidden parts, such as bolts, the associative symbol helps you check that you picked the right creation points for the dimensions. If the dimension line does not have an associative symbol, the dimen-sion is not associative.


Example 1 Modification: grid coordinates changed in the model:

Before:

Grid dimensions in the drawing:

After:

The grid dimensions are updated to reflect the changes:


Example 2 Modification: The right column is moved 500 mm to the right:

Example 3 Modification: Column height 1 modified in the model.

Before:

Various marks and dimen-sions manually added to a general arrangement draw-ing:

After:

After moving the right column 500mm to the right, the manual marks do not change.


Deleting and editing model objects

If you delete an object in a model, the corresponding drawing objects are also deleted in drawings.

Before:

A parametrized part is dimensioned in a drawing:

After:

After column height 1 is modified in the model, the dimen-sions automatically update in the drawing:


If you change the ID of a part in a model, the related drawing objects will not be updated if the model changes.

To prevent drawing views from being deleted when associated objects are removed from the model, use the following variables:

• Set variable XS_INTELLIGENCE_DO_NOT_REMOVE_OBSOLETE_VIEWS to TRUE, to prevent obsolete views from being deleted from drawings. FALSE is the default.

• Set variable XS_INTELLIGENCE_DO_NOT_REMOVE_OBSOLETE_VIEWS_IN_GA to TRUE to prevent obsolete views from being deleted from general arrangement drawings. TRUE is the default.

To set these variables, go to the Drawing properties category in the Advanced options dialog box (no restart required), or manually edit the batch files. For more information on variables, see Batch file settings in the user interface (p. 84).

Models created with earlier versions

Only objects created in Tekla Structures 11.0 are associative. For example, if you add dimension to a drawing created with earlier version, only dimension added in Tekla Structures 11.0 will be updated if the model changes.

Current limitations

Drawing objects such as lines, polygons, and circles are not associative in Tekla Structures version 11.0.

Grid dimensions are associated with the grid line name.

If you rename grid lines in a model, Tekla Structures deletes the grid dimensions associated with them in the drawings.

To prevent Tekla Structures from automatically updating draw-ings if the model changes, clear the Value field for the variable XS_INTELLIGENT_DRAWING_ALLOWED, in the Draw-ing properties category of the Advanced options dialog box.

Set variable XS_INTELLIGENT_DRAWING_ALLOWED_IN_GA to FALSE to prevent general arrangement drawings from being associative. Note that this prevents your part marks and dimen-sions to be automatically updated when the model changes.


Dimensioning improvementsTekla Structures 11.0 includes new options to define the format of equal dimen-sions in assembly, single-part, and cast unit drawings.

1. In the drawing properties dialog box, click Dimensioning..., to open the Dimensioning properties dialog box.

2. To select the format to use when combing equal dimensions, select a format in the Combine equal dimensions field on the Position dimensions tab, the options are 3*60 or 3*60 = 180:

3. To define how many equal dimensions must exist before they are combined, enter a number in the Minimum number to combine field.


For example:

Current limitations

Combine equal dimensions feature does not work with US absolute and US abso-lute 2 dimension types.

Combine equal dimensions set to Off:

Combine equal dimensions set to 3*60=180, and four equal dimensions (1200 mm) are combined:


Dimension line tagsIn Tekla Structures 11.0 you can add user-defined text tags to dimension lines for both single and combined dimensions:

To add dimension line tags:

1. Double-click the dimension line to open the Dimension properties dialog box.

2. Go to the Tag tab, and enter the dimension line tags.

Unfolding fixesTekla Structures 11.0 includes the following fixes:

• Bend angles in unfolded plates are now visible in multi-drawings.

• The Unfolded option in the View properties dialog box of single part, assembly, GA and multi drawings now works correctly:

• You can now only update dimensions by recreating the view in the drawing level view properties.

• Set the variable XS_UNFOLDING_PLANE_EPSILON to define epsilon when checking if all section points are in the same plane. The default value for this variable is 0.01 mm. To set the variable, click Tools > Advanced options, and go to the Speed and accuracy category.


Weld symbol improvementsNew attributes available for weld symbols in drawings: Effective throat and Root opening.

See also New weld options (p. 138)

Drawing list improvementsThe Drawings dialog box includes the following improvements:

• Renamed columns, see illustration below• Title fields in the drawings list• Include up to 20 user-defined attributes in the drawings list.

Root opening Effective throat

Title column renamed Name

Name column renamed Mark

Title fields contains the drawing titles defined in the Drawing properties dialog box:


User-defined attributes

To include a user-defined attribute in the Drawings dialog box:

1. To define a user-defined attribute in the drawing properties: click User-defined attributes... in the drawing properties dialog box:

2. To display user-defined attribute in the Drawings list, you must set special_flag (formerly consider_in_numbering) to yes for the user-defined attribute in the objects.inp file:

3. Close Tekla Structures and restart the program to activate your changes. The user-defined attributes you defined now appear in the Drawings dialog box.

Opening drawings

Checking of drawings is now made much easier and faster than before. From now on, you can keep the drawing list closed while going through the drawings, as you can Open next (default shortcut Ctrl+Down) or Open previous (default shortcut Ctrl+Up) drawing without having to pick them from the drawing list.

See also Common drawing properties in the online help.

User-defined attributes in drawings in the online help.


Elevation dimensionsIn Tekla Structures 11.0 you can modify how elevations are dimensioned using the Datum point for elevations field on the Attributes tab in the drawing view prop-erties dialog box:

The datum point is a reference point relative to which the elevations are calcu-lated. You can define different datum points for drawings and views.

Datum point for elevations is 0


Improvements to section view symbols and labelsTekla Structures 11.0 displays specific information in section view symbols and labels:

To specify which section view symbol to display:

• In the Section symbol properties dialog box, select an option in the Symbol list box.

To modify section labels:

• Open the View properties dialog box by double-clicking the border of the section view. On the Label tab, enter the label text in the Text field.

Section view symbol

Section view label

Both: Left: Right:


• To restore the default label text, clear the Text field.

Drawing colorBy default drawings have a white background and black lines.

Templates and reportsTekla Structures 11.0 includes the following new features and fixes:

Report file locationTo define the default folder for reports, enter the path in the variable XS_REPORT_OUTPUT_DIRECTORY:

Go to the File locations category in the Tools > Advanced options dialog box.

To output a report to a different folder, rather than the default location, include the full path of the folder in the Report file name field in the Report dialog box.

Custom seams in reportsTo include seams in reports, use the following new template fields:

• SEAM_NAME • SEAM_LENGTH

Fixes• Drawing and project user-defined attribute values are now correct in

ASSEMBLY and ASSEMBLY_PART type templates.

• The ASSEMBLY_TOP_LEVEL field now includes the top level of the part, even if the solid is cut.

To create colored drawings, set the variable XS_USE_COLOR_DRAWINGS to TRUE (go to the Drawing view category in the Tools > Advanced options dialog box).

To change the drawing color in the drawing editor, click Setup > Black and white drawing, or use the keyboard shortcut b.


• The ASSEMBLY_WEIGHT field in part marks now calculates the weight of the assembly from all objects in the assembly, even if the whole assembly is not within the drawing view.

• The report fields FLANGE_LENGTH_U, FLANGE_LENGTH_B, WEB_LENGTH now display the correct lengths.

New surface treatment fields in report templatesYou can include the following new surface treatment fields in report templates:

Miscellaneous

Part marks• Part marks are now oriented to match beams.

• Create > Part marks > All parts did not work correctly. Now Tekla Structures ignores the visibility settings and creates marks in all existing views.

• Option type user-defined attributes now return the text value to part marks instead of zero.

Name ExplanationNAME Text in the Name field in the Surfacing proper-

ties dialog box.SURFACING_CODE Code for the surface treatment defined in the

product_finishes.dat file. For example, TS1.

SURFACING_NAME Surface treatment name defined in the product_finishes.dat file.

SURFACING_TYPE Surface treatment type in the Surfacing proper-ties dialog box.

SURFACING_TYPE_NUMBER Surface treatment type number defined in the product_finishes.dat file.

SURFACING_AREA

SURFACING_VOLUME

SURFACING_WEIGHT

The NAME field in report templates displays the text entered in the Name field in the Surfacing properties dialog box.


Placing text in drawings• Changing text created with Text along line command placing from

Fixed to Free in the Text placing dialog box no longer generates an application error.

• The Angle field in the Text properties dialog box is now grayed out if you use the following types of text:

• Text along line• Along line, arrow at start point• Along line, arrow at end point

Drawing hatchesTo speed up opening drawings that contain hatches, Tekla Structures now buffers hatches. Use the following variable to adjust the size of the buffer: XS_HATCH_SEGMENT_BUFFER_SIZE.

The default value is 100000. If the drawing contains very complicated hatches, try using a larger value. For small hatches, use a smaller value. You do not need to restart Tekla Structures to activate changes to this variable.

Grids• Sometimes Tekla Structures combined the grid lines of several draw-

ing grids. Fixed.

• When you moved a model grid in a drawing’s x and y directions, the drawing grid and any manual edit were deleted and a new grid cre-ated. Fixed.

• Grids created in the model after creating a drawing now appear cor-rectly in the drawings.

Fixes• In general arrangement drawings, parts not completely within the

drawing view are now left open. This applies also affects section views. ,

• Bevel dimensions now appear on the face of plates, not the edge.

• The layout field was not recognized when you modified drawings, only "table layout" field was recognized. Fixed.

• If a bolt or bolt hole was located near the boundary of a drawing view, opening a drawing sometimes locked up Tekla Structures. Fixed.

• Modifying the properties of a multi-drawing deleted the update flag, so you could open the multi-drawing even if it was not updated. Now if some drawings have an update flag, Tekla Structures prompts you to update the drawing:


• Select Yes to update and modify all selected drawings,

• Select Cancel to only modify up-to-date drawings and ignore those with an update flag.

• Section symbols appeared in the wrong place if you created section view from a rotated view. Fixed.

• Modifying the Section symbol offset value at the drawing level caused the whole drawing to be recreated. Fixed.

• Sometimes when you double-clicked an absolute dimension to open the Dimension properties dialog box, Tekla Structures used the rela-tive dimension type, instead of the absolute. Fixed.

• Tekla Structures 11.0 displays a warning on the status bar if you try to modify the protection settings of a frozen drawing.

• You can now also snap to reference objects in drawings using the Geometric points snap switch.

• Grid lines now correctly snap to the edges of a shortening cut, instead of disappearing.

• If a general arrangement drawing contained studs and bolt presenta-tion was set to solid, opening a general arrangement drawing was sometimes slow. Fixed.

• Sometimes when printing a landscape report the text was too narrow. Fixed.

• The Arial and Arial Narrow fonts no longer appear the same in draw-ings.

• Selecting GA drawings from the Drawing list and modifying them with the General arrangement drawing properties dialog box now cor-rectly modifies all properties.

• Plotting a drawing to DXF or DWG file no longer changes font width.

• The Plot dialog box no longer rounds up the drawing scale up to the next decimal place.

• Line weight no longer appears too thin in black and white mode when you print a drawing.

• Symbols moved in drawings using drag and drop now no longer move back when you modify them.

Miscellaneous fixes (p. 121)

Import MicroStation 8 DGN filesTekla Structures 11.0 imports MicroStation 8 dgn files. Tekla Structures exports dgn files in MicroStation 7 format.

IFC import and exportTekla Structures includes the following new features:

IFC Reference Import

Import IFC2x2 models (IfcBuildingElement class and sub-classes only) as refer-ence models. This means you can use data from architectural software, such as ArchiCAD, Allplan, Bentley Architecture, and ADT.

For more information on using reference models, see Reference models in the online help.

Tekla Structures supports only IFC2x2 reference files, you can see the file format in the IFC file header:

IFC Export Tekla Structures 11.0 exports both IFC2x and IFC2x2 files. It exports the follow-ing entities:

• IfcBeam• IfcColumn• IfcSlab• IfcWallStandardCase• IfcPlate


• IfcFooting• IfcPile• IfcRailing• IfcBuildingElementPart• IfcBuildingElementProxy

Use IFC export tab in a part’s user-defined attributes dialog box to define how to export parts:

See also For more information on the properties on the IFC export tab and how to export IFC files, see Exporting IFC in the online help.

Current limitations

• IFC export does not support tapered members

• Some special profiles are not supported.

• Exporting curved beams is not always working correctly.

• In some cases polybeams are placed and rotated incorrectly.


Web viewer modelsTekla Structures 11.0 imports webviewer models in XML format as reference models.

Miscellaneous fixes• When you use the variable XS_USE_NEW_PLATE_DESIGNATION

Steel 2000 and KISS exports now contain the correct values.

• When you set the variable XS_DGN_EXPORT_USE_LOCAL_ID to TRUE to use the local ID in 3D DGN export, it now works correctly.

• Importing the entire profile catalog from any environment to the UK environment did not work if the existing catalog already contained a cross-section with same name and the suffix _ 2. Now the imported cross-sections have the suffix _3, _4, etc.

• Adding DXF files to a drawing no longer generates extra lines between bolts.

• Profile rotation values in SDNF files are no longer doubled when importing.

• Selecting Export all in 3D DGN exports no longer causes the export to fail.

Performance improvements• Tekla Structures 11.0 creates and modifies custom components faster

than previous versions.


• Tekla Structures no longer recreates custom components when saving in multiuser mode, which makes the save faster, particularly for slow hard disks or if logs are written to a network drive.

• Custom components that contain hundreds of parts now work faster.

When you copied custom connections to a model, or imported or exported them, Tekla Structures copied the system connections within custom connections as custom connections. This increased the size of the xslib.db1 and slowed down opening the model. This has been fixed, but this fix does not correct the results of this problem in existing custom component libraries. To fix an existing custom component library:

1. Backup the model.

2. Open the model.

3. Export all custom components.

4. Close the model and Tekla Structures.

5. Delete xslib.db1 from the model folder.

6. Open Tekla Structures and the model.

7. Import the custom components into the model.

8. Save the model.

New properties for custom componentsTo include an option to create or not create parts in a custom component proper-ties dialog box:

1. In the Variables dialog box, add a new property

2. Set the Value type to Yes/No,

3. Set Visibility to Show

4. Enter a Label to display in the custom component dialog box:

5. In the custom component browser, link the property to a part:


6. Save the custom component and exit the custom component editor.

When you open the custom component properties dialog box, you now have the option to create or not create the part:

Editing custom componentsTekla Structures 11.0 stores edited custom components separately to the original custom component:

• When you create a custom component, Tekla Structures saves a library definition of the custom component in the file xslib.db1 in the current model folder.


• When you edit a custom component, Tekla Structures shows the library definition of the component in the editor, and the modifica-tions you make are saved to the xslib.db1 file.

The main benefits of storing edited custom components to the library definition are:

• You can edit custom components from the component catalog, by right-clicking the component and selecting Edit custom component.

• You can edit any custom component imported into the component catalog, not only the ones in the current model.

• The difference between the custom component in the model and the component you edit in the custom component editor is now more clear.

• You see the unmodified custom component in the editor.For example, if a custom component uses the Creation option, Tekla Struc-tures shows the library definition of the component in the editor, with all parts visible, even if you set the create parts option to No in the current model.

If you remove the xslib.db1 file from the current model folder, you cannot edit or export custom components.


Components created in earlier versions

Tekla Structures 11.0 handles outline planes differently. Plane names are more descriptive and the distances bound to outline planes of asymmetrical profiles are more effective.

Custom components created with earlier versions that includes distances bound to outline planes may not work correctly in version 11.0.

When you open an old custom component in the new Custom component editor, Tekla Structures asks if you want to update the component. The options are:

• Yes: The component is updated to Tekla Structures version 11.0. If you update the component, check the component in the editor, especially the distances.

• No or Cancel: The component is not updated, and will work in the same way as in the previous version.

See also Editing custom components in the online help.

Define parameters for part addsIn Tekla Structures 11.0 you can:

• Bind part adds using distances• Move parts adds using magnetic planes and lines• Calculate the properties of part adds using formulas

For more information, see Parametric modeling and Part add in the online help.

Imperial units in formulasNow you can use imperial units in formulas, for example, define the name of a profile using a formula in the Custom component editor. Use the imp operator in the same way as any other operator, e.g. sin().

When you use the imp operator in a formula, Tekla Structures converts the impe-rial unit to millimeters, then performs the calculation you define in the formula.


Use the following formats to identify feet, inches and fractions:

New detail position optionsTo position custom details on contour plates and concrete slabs, use the new field Position in relation to primary part on the General tab of the detail properties dia-log box:

Select a checkbox to indicate the position of the definition point of the detail, rel-ative to the main part.

Use the Horizontal offset and Vertical offset fields to define the horizontal and ver-tical alignment of the detail, relative to the primary part.

MiscellaneousTekla Structures 11.0 includes the following fixes:

Market size functionThe Custom component editor includes a new parameter, fMarketSize(), which gives the next available market size for the material, based on the thick-ness you specify. The syntax is =fMarketSize(material, thickness, extrastep):

• Insert the material as a string with in the parentheses.

• For extrastep enter an integer to define the increment to the next size (default is 0).

Format Example Meaning Resultimp(x) imp(1) 1 inch 342.90mmimp(x,x) imp(1,2) 1/2 inch 38.10mmimp(x,x,x) imp(1,1,2) 1 1/2 inches 12.70mmimp(x,x,x,x) imp(1,1,1,2) 1 foot, 1 1/2 inches 25.40mm


Fixes• Exploding a custom part by clicking Detailing > Explode component

and picking the custom part now works.

• When you used the graphic options in list boxes in the custom com-ponent dialog box the settings did not change. Fixed.

• Parts created with custom component now get the current phase num-ber.

• Mapping properties in nested custom components now works cor-rectly.

• The minimum size of the component catalog has been reduced. Use the following variables to adjust the size, then re-open the component catalog:

• Collection names are truncated to 12 characters. To change this, use Advanced options > Modeling > XS_COMPONENT_CATALOG_COLLECTION_NAME_LENGTH. This may increase the size of the component dialog box.

• To adjust the size of thumbnails to between 6 and 96 pixels, use Advanced options > Modeling > XS_COMPONENT_CATALOG_THUMBNAIL_SIZE . The default is 96 pixels.

• Position in relation to primary part no longer disappears from the com-ponent dialog box if you modify the component in the Custom com-ponent editor.

Component catalog improvementsThe Component catalog contains the following new features in Tekla Structures 11.0:

Detail and thumbnail view

Browse component names or thumbnails:

Detail view:


Thumbnail view:


By default, components are grouped in folders based on their type and framing condition. You can add and remove components, and create folders and subfold-ers.

Information on the folders you create is stored in the file ComponentCata-logTreeView.txt located in the attributes folder in the current model folder.

The default tree settings are stored in the file ComponentCatalogTree-View.txt file, located in the folder ..\TeklaStructures\11.0\environ-ments\*your environment*\system.

If you modify the default tree, your settings are stored in the current model folder.

To create new folders in the tree view, right-click a level in the tree and select an option from the popup menu:

• Create new folder to create folder at the same level• Create new sub-folder to create a folder one level below

Grouping components

To create a new folder based on the results of a search:

1. In the Component catalog, enter your search criteria and click Search.

2. To group the search results in a new folder, click Store.

3. In the Store search result dialog box, enter a name for the folder and click OK.

4. The new folder appears in the tree.

To remove components from a group, right-click the component and select:

• Remove, if it is a default group.or

• Remove from search result if the folder was created from a search


Add or edit thumbnail images

To edit a thumbnail image for a component:

1. Create an image and save it in bmp format in ..\Tekla Struc-tures\11.0\nt\bitmaps folder.

2. Press CTRL-f to open the component catalog.

3. Right-click the component and select Change picture...

4. Locate the thumbnail and select it:

5. Click OK.

6. Tekla Structures links the thumbnail to the component.

Add or edit descriptions

To add component descriptions or edit existing ones:

1. Click to view the description field in the lower section of the catalog window.

2. Select a component.

If you click Delete, the component is deleted from the model. To remove a component from a group, always use Remove com-mand.

To create the image, you can use Component basic view and Snapshot commands, for example.


3. Enter new text or edit the existing text.

4. Click in the model. Tekla Structures prompts you to save the description. Select Yes to save it.

Descriptions you add or edit are stored in the current model folder in the file ..\attributes\ComponentDescriptions.csv.

To use your component descriptions in other models, move the file to the system folder: ...\TeklaStructures\11.0\environments\*your environ-ment*\system.

Add or edit keywords

To add or edit keywords, right-click a component in the component catalog, and select Edit keywords...

Keywords you add or edit are saved in ComponentCatalog.txt file in the cur-rent model folder.

You can combine ComponentCatalog.txt files and move them to the system folder: ...\TeklaStructures\11.0\environments\*your environ-ment*\system..

Tekla Structures searches for the files in the following order:

Customize and save components

Many components are suitable to use in different situations. Now you can define the properties of a component to use in a specific situation, then save a copy in the component catalog to use in similar situations.

Folder Defined byCurrent model The open modelProject variable XS_PROJECTFirm variable XS_FIRMSystem variable XS_SYSTEM


For example, we’ll use the Bolted gusset (11) component as a single brace at the base plate of column.

5. To save a copy of the component, we’ll right-click the component symbol in the model, and select Publish in catalog.... The Publish in catalog dialog box appears.

6. We can add the component to a specific group. By default, the component is added to the All group.

7. By default the component uses the same thumbnail image as the original component. To change the thumbnail, see Add or edit thumbnail images (p. 131).

Miscellaneous • Adding more than 255 characters to the description field generated an application error. Fixed.


• Searching for components by number now works correctly. For example, if you type 11 in the search field, the search results are con-fined to components that have the number 11.

• Collection has been renamed Search result.

Use Excel in connection designIn Tekla Structures 11.0 you can link Microsoft Excel files with system compo-nents to perform calculations and automatically update connection properties. This is useful when you want to check connection design and have Tekla Struc-tures update component properties according to specific codes.

You need a component-specific spreadsheet.

• The spreadsheet file names and locations are defined in the file Excel.vb, located in the ..\nt\bin\plugins folder.

• The default name for component spreadsheets is component_*com-ponent number*.xls

• The default location for spreadsheets is ..\11.0\environ-ments\country-independent\exceldesign folder.

The folder ..\11.0\environments\country-independent\excelde-sign contains the following files to help you to create your own spreadsheets:

The template file includes following sheets:

• InputsTekla Structures transfers the component properties from the component properties dialog box to this sheet.

• ComponentTekla Structures transfers the component geometry and information on the main and secondary parts (for example, part profiles) to this sheet.This sheet includes calculations.

• OutputsExcel adds modified values to the Outputs sheet. These values are trans-ferred back to the component, and the component is modified accordingly.

File name Descriptioncomponent_144.xls A sample file for component End plate

(144). component_template.xls A template for creating your own spread-

sheets.


See also Using Excel in connection design in the online help.

MiscellaneousTekla Structures 11.0 includes the following features and fixes:

• Macro symbols were selected but not highlighted in rendered views if parts of the macro were hidden. Fixed.

• The default color of construction lines created by a component has been changed from black. Lines located inside the work plane are yellow and lines outside the work plane are red.

• Tekla Structures 11.0 now automatically applies values in component dialog boxes before a save. This ensures that values in sub dialog boxes (Bolt or Weld) are also saved.

To perform calculations, the Excel spreadsheet must contain the StartCalculation macro, which is included in the template file.

You just use the sheet names shown in the template file.

6.2 DrawingsFixes• The variable XS_BOLT_POSITION_TO_MIN_AND_MAX_POINT now

works correctly. Use the variable to dimension minimum and maxi-mum position for bolts. This variable can be used only when the dimension point is inside the bolt group, not when the point is, for example, in the part end.

• Positioning secondary parts (e.g. gusset plate) using By bolt dimen-sioning now creates horizontal and vertical dimensions both to the same hole:

• Sometimes parts at the left end of an assembly were used when calcu-lating drawing view boundaries for an end view from the right end of the assembly. Fixed.

• Sometimes part cuts in the end of an assembly were included in the overall dimension of the part. Fixed.

• For Oversized bolt holes for bolts that did not have a slot value, bolt marks and bolt symbols were incorrect in drawings. Fixed.

• Tekla Structures 11.0 only relocates marks if the model changes.

• Sometimes slots appeared in the wrong direction in drawings. Fixed.

New help for tower and bracing componentsThe help for tower nd bracing compnents has been rewrittend and terminology made more consistent in the component dialog boxes. :

Improvements to existing moment connection checksThe moment connection check has been improved as follows:

• Checks added for bolt hole edges, end distances, and spacing that are not stress-related


• Tekla Structures now reports buckling check results for lower flange plates if they are compressed

• New Net Tension Capacity and Gross Tension Capacity checks for shear plates

• Distribution of axial forces is now based on the relative area of the secondary members (flanges and web)

• New check for buckling length

• Results are shown using four digits

US DesignThe values for Fv and Ft for various bolt scenarios are hard-coded in Tekla Struc-tures. If you use an non-standard material grade, Tekla Structures uses the values Fv=17 kips and Ft=44 kips and adds a note to the report.

AutoConnection improvementsTekla Structures 11.0 includes the following fixes:

• Using AutoConnections where beams did not touch the column caused application error. Fixed.

• AutoConnection did not connect parts that were not touching, even if the variable XS_AUTOCONNECTION_TOLERANCE was set.

Beam to beam connectionsTekla Structures 11.0 includes the following new features and fixes:

Full Depth S (185)If the primary part was a U-profile with angled flanges, the gusset shape was not always correct. Fixed.

In the French environment, Tekla Structures did not create the connection if the primary beam was a U-profile. Fixed.

Purlin connection (93)With small rafters (< 120mm) bolts no longer penetrate both flanges.

Beam with stiffener (129)This connection now creates a correctly-shaped shear plate.

Two sided clip angle (143)This connection now creates correct angle plates with default values.


Beam to column connectionsTekla Structures 11.0 includes the following new features and fixes:

Bolted moment connection (134)Slotted or oversize hole settings for bolts in the shear plate no longer override the hole settings for the flange plate.

• Define tile and mortar colors by assigning values for red, green, and blue, on a scale of 0 to 10. For example:

Red = 10 0 0Green = 0 10 0Blue = 0 0 10White = 10 10 10Black = 0 0 0

5. Click Modify and Apply to save the tile pattern properties.

6. To add the tiled surface treatment to a part, use the Create polygon surfacing or Create face surfacing command:

• Pick the corners of the surface treatment or pick the part face,

or

• Pick the origin and the direction of the surface treatment.

To create tiling that runs continuously from one part to the next, pick the same origin for the surface treatment for all the parts:

Tekla Structures only displays the tile pattern in rendered views.

See also Show tiled surface treatment in drawings (p. 155).

Miscellaneous• Magnetic planes did not work correctly with polygon plate handles,

because the center line of the polygon plate was incorrectly drawn. Fixed.

• Tekla Structures 11.0 creates rectangular reinforcing mesh in the direction of the current work plane if you try to create another direc-tion. For example, if the work plane is the horizontal XY plane and you try to create the mesh in the vertical direction.

• When you use the the Inquire command on reinforcing bars, the rein-forcing bar is highlighted, not just the main part.


• If you added a steel part inside a concrete part cast unit and changed the embedded part, you could still open the cast unit drawing without running numbering. Fixed:

• You cannot open cast unit drawings if embedded objects have changed.

• Cast unit drawings are flagged P for numbering purposes, even if only embeds have changed.

Cast unit drawing improvementsTekla Structures 11.0 includes the following new features and fixes:

• Create cast-unit drawings of main concrete parts and cast-in embeds (steel parts or assemblies added to a cast unit).

• Modify bolt and weld properties using the Bolt..., Bolt mark..., and Weld... buttons in the Cast unit drawing properties dialog box.

• Automatically dimension the main parts in steel assemblies in draw-ings. The Cast unit - dimensioning properties dialog box now includes a Bolt dimensions tab and new options on the Position dimensions tab. For more information see Bolt dimensioning properties and Posi-tion dimensioning properties in the online help.

Tekla Structures compares embeds and will not open the draw-ing, even if embedded objects are not selected in numbering setup.


• To automatically open the drawing view in the drawing editor when you create a cast unit drawing, hold down the Ctrl and Shift keys and click Drawing > Cast unit drawing.

This also works for assembly and single-part drawings.

• When you used the Model option for Coordinate system in the Cast unit - view properties dialog box, plates were incorrectly oriented and the view direction was not taken into account. Fixed.

• If you clicked the Apply button before the Modify button in Cast unit - bolt properties, Cast unit - bolt mark properties, and Cast unit - welding properties dialog boxes, the properties were not modified. Fixed.

Show undeformed shape of parts in drawingsTo create drawings that show parts in their fabrication state, rather than their deformed state:

1. Open the drawing properties dialog box and click the View... button.

2. Go to the Attributes tab and select Yes in the Undeformed list box.

3. Click Apply or OK to save the drawing view properties.

4. Create the drawing.

Reinforcement marks and dimension linesTekla Structures 11.0 includes the following improvements:

• Leader line type Mark parallel to the rebar added for rebar marks (not merged rebar marks).

• New arrow type showing a circle at the end of the leader line added for rebar marks

• If a rebar dimension line is dragged outside the rebar group, Tekla Structures 11.0 draws a broken line from the rebar to the dimension line.

• If a rebar mark has a leader line and a rebar dimension line, the rebar mark leader line now follows the intersection of the rebar line and the rebar dimension line.

Topics Corbel connection (14) (p. 161)

Seating with dowel connections (p. 161)


Corbel connection (14)The sloped secondary part is now correctly cut and the cut is wider..

Seating with dowel connections• The holes for the dowels in the beam were rectangular. A new round hole

option has been added to seating connections (75), (76), (77), and (78).

• An option to omit the end cut has been added to seating connections (75) and (77). This is required for multi-span beams.

• An option to use a single bearing pad aligned with the column has been added to seating connections (76) and (78). This option overrides the align-ment options on the Left beam and Right beam tabs. The dimensions and eccentricity of the bearing pad comes from the values for the left beam. If the eccentricity values on the Picture and Left beam tabs are zero, the bearing pad is created to the middle of the end of the column.

• Seating connection(75) no longer creates too large a bearing pad.


• Column end cuts have been corrected in two-sided seating connec-tions (76) and (78) for beams that are not parallel or with lower planes at different levels.

• The bearing pad is now automatically part of the column assembly. To prevent this, define a specific assembly number for the bearing pad in the component dialog box. This applies to seating connections (75), (76), (77), and (78).


• When you modified a system component that added parts to a cast unit it sometimes removed other parts from the cast unit. Fixed.

• Cut parts created by concrete components generated warnings in the log file. • Setting part representation to Fast in the View setup dialog box

did not display polygon plates and cuts correctly. Fixed.

7.4 ReinforcementThis section describes the following new features and fixes:

Topics Spiral reinforcement groups (p. 162)

Reinforcement mesh properties (p. 164)

Reinforcement components (p. 166)


Spiral reinforcement groupsIn Tekla Structures 11.0 you can model circular or polygonal spiral reinforcing bar groups.

Create the spiral reinforcing group using the Reinforcing bar group or Circular reinforcing bar group tools


Example To create a circular spiral reinforcing bar group:

1. Double-click the Create circular reinforcing bar group icon to open the Reinforcing bar properties dialog box.

2. On the Group tab, select Spiral in the Rebar group type list box:

3. Enter or modify other properties, if required.

4. Click Apply or OK.

5. Select the part.

6. Pick three points to define the stirrup.

7. Pick two points to indicate the distribution of the bars.


8. Tekla Structures attaches the spiral reinforcement to the part.

See also Reinforcing bar group in the online help.

Reinforcement mesh propertiesThe Reinforcement mesh properties dialog box includes several new properties:

Field DescriptionMesh Click to select a mesh from the mesh catalog. Tekla

Structures applies the following properties to the mesh type: Diameter, Pitching, Left overhang and Right over-hang.

Does not define the size of the mesh.Creation method Defines whether the bars are evenly distributed or not,

for both longitudinal and crossing bars.


Tekla Structures takes the default properties for mesh from the file mesh_database.inp, located in the ...\environments\*your environ-ment*\profil folder.

Pitching (previ-ously spacing)

In previous versions, this was called spacing. Use the Pitching fields to define the pattern of both longitudinal and crossing bars:

You can use more than one pitch value. For example,

Longitudinal: 3*200 3*600 2*100

Cross: 4*200 4*100

If you define several pitch values, you cannot manually define the dimensions of the mesh. Tekla Structures auto-matically calculates the width and length of the mesh using the values in the Pitching, Left overhang, and Right overhang fields.

The Mesh type option you select also affects which dimensions you can manually enter.

Left overhangRight overhang

Define the overhang of longitudinal and crossing bars. These options are only available when Creation method is set to By varying spacings.

Field Description


Reinforcement componentsTekla Structures 11.0 includes the following new features and fixes:

Reinforcement mesh array in area (89)Use the component Reinforcement mesh array in area (89) to create reinforcement meshes for an entire concrete part, or for a defined polygonal area:

To use:

1. Pick the part.

2. To attach the reinforcement to the entire part, pick the first position,

or,

to attach reinforcement mesh to a selected area, pick points to indicate the polygonal shape of the reinforcement.

3. Click the middle mouse button to create the reinforcement mesh.

FIxes When you define more than one set of distances in the Bar pitching field, e.g. 10*200 15*200, this component now uses them all, not just the first one.


Automated reinforcement layout componentsTekla Structures 11.0 includes the following new components to create reinforce-ment for different types of concrete parts:

Component DescriptionAutomated reinforce-ment layout - double tee beam (51)

Create flexural, shear or flange reinforce-ment for double tee beams.

Automated reinforce-ment layout - Inverted tee beam (52)

Creates flexural, shear or ledge reinforce-ment for inverted tee beams.

Automated reinforce-ment layout - Ledge beam (53)

Creates flexural, shear or ledge reinforce-ment for ledge beams.

Automated reinforce-ment layout - rectangular beam (54)

Creates flexural or shear reinforcement for rectangular beams.


Modeling slab areasUse the Modeling of slab area (88) component to create various types of concrete slabs, including fanned layouts. This component creates slabs between two sup-port lines, which can be polylines or sloped. To create a fanned layout, use sup-port lines that are curved or of different lengths.

For more information, see Modeling of slab area (88) in the online help.

Automated reinforce-ment layout - ledge span-drel (55)

Creates flexural, shear or ledge reinforce-ment for ledge span-drels.

Automated reinforce-ment layout - rectangular spandrel (56)

Automated reinforce-ment layout - columns (57)

Creates longitudinal or tie reinforcement for columns.

Component Description


Slab bars (18)The Slab bars (18) component includes following new features:

• Group offsets from the edge of the slab.• Support for curved and tapered rebar groups.• Main and cross bar extensions.• Cover thickness options on the Bottom bars and Top bars tabs.

Lifting anchor (80)You can now can define Class for lifting anchors.

Pad footing (77)D-type lacer bars are now centrally placed so that they are identical. With the fol-lowing lacer types default 'p1' and 'p2' values are half the length of the side of the pad footing:

Rebar spacing is now correctly calculated:

• To create a rebar group with exact spacing and flexible first and last spaces, select the One zone option in the Arrangement field and the Spacing option in the Creation method field.

• To create a rebar group in three zones, with exact spacing and a flex-ible first space, select the Three zones option in the Arrangement field and the Spacing option in the Creation method field for the first zone.

• To create a rebar group in three zones, with exact spacing and flexi-ble first and last spaces, select the Three zones option in the Arrange-ment field and the Spacing option in the Creation method field for the middle zone.

• To create a rebar group in three zones, with exact spacing and a flex-ible last space, select the Three zones option in the Arrangement field and the Spacing option in the Creation method field for the third.

Pilecap reinforcement (76)Rebar spacing is now correctly calculated.

To create a rebar group with exact spacing and flexible first and last spaces, select the By spacing option in the Creation method field.

Beam end reinforcement (79)The diagonal bar no longer protrudes from the beam.


Rectangular column reinforcement (83) You can now select hook type for each intermediate link groups.

Miscellaneous• When comparing bent meshes, spacing were not always correctly

compared. Fixed.

• Bent meshes were given unique position numbers. Fixed.

• Reinforcing bars that were not perpendicular to the view plane were not visible in cross section views. Fixed.

• Cover thickness was not always created correctly for polygonal meshes. Fixed.


8 Tekla Structures 11.0 Analysis and design

8.1 Analysis and designThe Tekla Structures 11.0 Analysis and Design module contains the following new features and fixes:

Topics Extended clash check (p. 171)

New design codes (p. 172)

New seismic codes (p. 172)

Analyzing composite beams (p. 173)

Load groups (p. 174)

Changes in ULS and SLS design checks (p. 175)

Load distribution fixes (p. 176)


Extended clash checkExtended clash check is now the default method for creating analysis models. It is based on a clash check of solids. By default, solids are expanded by 1mm in each direction to find parts that are so close to each other that they should be automat-ically connected when creating the analysis model.

To automatically connect parts in the analysis model, even if they have a large tolerance gap you can change the expansion in the axial direction using the vari-able XS_AD_SOLID_AXIAL_EXPAND_MM.

If this variable is not set, the default value of 1mm is used.


New design codesThe following design codes have been added for steel:Desi

The following design codes have been added for concrete:

See also Design codes and methods in the online help.

New seismic codesTekla Structures 11.0 includes the following new seismic codes:

• IBC2003 (US)• AIJ (Japan)

If there is a connection between members, they are treated as clashing.

Option DescriptionAS 1250 Australian design code for steel SNiP-11-23-81 Russian design code for steel AIJ Japanese design code for steel

Option DescriptionAS 3600 Australian design code for concreteSNiP-2.03.01 Russian design code for concreteAIJ Japanese design code for concrete


Analyzing composite beamsComposite construction consists of beams, studs and concrete slab on top of the beams. To analyze beams as composite beams, modify the beam properties on the Analysis tab:

1. Select:

• Composite beam to manually change composite beam properties, or

• Automatic composite beam: to have Tekla Structures automati-cally recognize composite beams and calculate the effective slab width

2. If you chose Composite beam, select the slab Material and Thickness.

3. Select Effective slab width:

• Enter the value, or


• Have Tekla Structures automatically calculate the effective slab width by dividing the span length of the beam by the value you enter. For example, if span length is 8.0 meters, factor 8 is used for both left and right. So the effective width of the slab is: ((0.5*8.0)/8) + ((0.5*8.0)/8), = 1.0 meter

4. Run the analysis to calculate the effective slab width.

• The effective width cannot exceed the maximum distance to the next beam:• For the Composite beam option, slab width is zero if there are no

adjacent beams.

• The Automatic composite beam option enables Tekla Structures to calculate slab width, even if there are no adjacent beams.

• Effective width must be less than half the distance to the nearest com-posite beam.

Inquiring effective width

Right click and select Inquire to see the analysis results. The results that relate to composite beams are:

• Effective width• slab thickness• slab material• concrete strength• rib width and height• stud diameter and length

Load groupsTekla Structures 11.0 includes the following improvements:

• You no longer need to create load groups before applying loads in the model.

• The dialog box name is now Load groups

• New Current field and Set current button in the Load Groups dialog box.

• You can select loads by load groups and load groups by loads.

• Right-click a load group to export or import it.


The Loads toolbar contains the following new options:

The default load groups are defined in the DefaultLoadGroups.lgr file, located in ..\TeklaStructures\11.0\environments\*your environ-ment*\system folder.

Changes in ULS and SLS design checksTekla Structures 11.0 distinguishes between Ultimate Limit State (ULS) and Ser-viceability Limit State (SLS) load combinations in steel codes EC3, BS, and AISC LRFD. In the previous version factored loads were generally used.

Tekla Structures 11.0 runs a deflection check for SLS load combinations, but not for ULS load combinations.

For ultimate limit state, ULS- and LG-type load combinations are considered.

For serviceability limit state, SLS- and LG-type load combinations are consid-ered.

The Analysis > Optimize menu contains the following new options:

Open Load groups dialog box

A list box to select a load group


• Analysis model parts

Optimizes only the parts included in the analysis model.

By default, Tekla Structures considers ULS and LG load combinations. Use the Serviceability limit state switch to also consider SLS and LG load combi-nations

• Selected parts

The same as Analysis model parts and also optimizes selected parts, and parts not included in the analysis model if their design group matches the design group of a part in the analysis model.

• Serviceability limit state

If limit state design is active, this option includes the serviceability limit state in the optimization.

Load distribution fixesTekla Structures 11.0 uses the load panel system as the default load distribution method.

Some limitations have been removed from the load panel system. Also, uniform load areas can now be any shape and can contain holes.

Tekla Structures 11.0 includes fixes for the following:

• There was error in load distribution if the new load panel system was used and the direction of the primary axis was incorrect. Invalid spanning direction is now automatically corrected, if double span-ning and automatic primary axis weight are used. The direction does not matter in this case.

• An unnecessary warning appeared in load distribution even if the load was correct in STAAD.Pro. Inquiring a load applied to a slab always generated a similar warning.

• If you used load panel distribution, Tekla Structures generated over-lapping member loads from a single load. This made it difficult to check loads in the STAAD.Pro post processor. Now Tekla Structures always merges loads from a single load.

• If you used load panel distribution, Tekla Structures distributed the area load to the wrong part.

• The load panel distribution method is now always used.

The Serviceability limit state option will be available in version 11.1.


• Loads were not distributed to walls and slabs using load panel sys-tem.

• A tolerance problem in load distribution caused missing area loads and differences in total line load.

• Load distribution sometimes created a point load at an incorrect node on a column. This also occurred with walls connected to columns, creating split nodes.

Miscellaneous

Fixes• Using the extended clash check method with parallel or nearly paral-

lel clashing members did not work correctly. Fixed.

• The AISC ASD connection check includes the following fixes:• SSL and LSL values were missing for bolt grades A325N,

A325X, A490N, and A490X where the hole type is NSL in AISC manual table I-D page 4-5. NSL = Long-or short-slotted holes normal to load direction.

• Design check calculations used a default bolt strength when you used bolt grades A325N, A325X, A490N, and A490X and the bolt group contained slotted or oversized holes. Fixed. Now uses the bolt strength defined in AISC manual.

• You can now define different offsets for the nodes at the start and end point of a concrete panel.

• When longitudinal analysis offsets were used on a beam, the loads applied on the beam were positioned incorrectly. Fixed.

• Analysis member offsets were not taken into account when creating node points on the edge of walls that contained door openings. Fixed.

• The full analysis model did not work correctly if it was created before creating any loads in the model. None of the loads created later were added to the analysis model. Fixed.

• The load form picture was not updated on the Magnitude tab, if you loaded saved properties. A similar refresh problem also affected load panel properties on all load dialog boxes, and analysis properties on part dialog boxes.

• Trapezoidal member loads were not generated correctly when mem-bers were outside the load plane.

• Extra nodes were created on beams due to incorrectly detected clashes with slabs or walls.


• Analysis sometimes failed for concrete panels and slabs, because the default plane for concrete panels was the top plane in the German, Indian, Dutch, UK, US imperial, and US metric environments. The default plane has now been changed to middle. The tolerance for checking loads are inside plates has also been increased.

• Moment release at the end of a beam connected to a wall panel was not applied in the analysis model. Fixed.

• Using the member end release method, the By connection option gave incorrect analysis results. The hard-coded default values for member end restraints of connections were incorrect. Fixed.

• Tekla Structures did not create a rigid link between a beam and a wall created using the column tool.

• Where walls connected in a corner, the node points of one wall effected all neighboring walls resulting in too dense a triangle mesh. Now the nodes are merged to form a single shared node.

• The size of analysis elements created for walls or slabs sometimes varied considerably resulting in badly-formed triangles. The Element size in the dialog box is now an approximate value. Tekla Structures automatically rounds it up or down to form elements of the same size.

• The analysis log is now cleared each time analysis is run.

• Accepting all optimization results was very slow if Analysis utility check was selected in the Colors dialog box. Fixed.

• Analysis optimization sometimes suggested changing a library pro-file to a parametric profile (for example RHS150*5 to RHS150*150*5) with the same cross-section area. Now the profile name is retained if the cross section area of the optimized profile and the original profile are within 1 mm2 of each other.

• Analysis sometimes did not run, because the analysis method option in the analysis model properties was sometimes blanked out. Fixed.

• The following problems that occured when applying horizontal line loads to walls have been fixed:

• The load had to be positioned exactly on the selected analysis plane (e.g. the middle plane).

• Areas of the load that were not on the wall disappeared.• Tekla Structures created nodes at the load point, even if nodes

already existed, which caused problems with element meshing.

• It was not possible to modify the load result created with Wind load generator (28) macro by double-clicking the load, when the compo-

nent objects select switch was active. Fixed.


• The Inquire command showed the default user-defined attribute value 2147483647. Modifying analysis-related user-defined attributes without the A&D module installed caused an internal error, which resulted in incorrect values for those user-defined attributes.
