INTRODUCTION TO PRO/E

Pro/Engineer is the software product of PTC (Parametric Technology corporation)

its initial versions were Pro/E 1, 2... up to 17. Later Pro/E launched sequentially

versions as Pro/Engineer 2000; 2000i, 2000i;2001, Wildfire 1.0; Wildfire 2.0,

Wildfire 3.0; Wildfire 4.0; and Wildfire 5.0. In 2011, PTC rebranded Pro/Engineer

as Creo Parametric. The current version of the software is 1.0

Created by Dr. Samuel P. Geisberg in the mid-1980s, Pro/ENGINEER was the

industry's first successful rule-based constraint (sometimes called "parametric" or

"variational") 3D CAD modeling system. The parametric modelingapproach uses

parameters, dimensions, features, and relationships to capture intended product

behavior and create a recipe which enables design automation and the optimization

of design and product development processes. This design approach is used by

companies whose product strategy is family-based or platform-driven, where a

prescriptive design strategy is fundamental to the success of the design process by

embedding engineering constraints and relationships to quickly optimize the design,

or where the resulting geometry may be complex or based upon equations. CreoElements/Pro provides a complete set of design, analysis and manufacturing

capabilities on one, integral, scalable platform. These required capabilities include

Solid Modeling, Surfacing, Rendering, Data Interoperability, Routed Systems

Design, Simulation, Tolerance Analysis, and NC and Tooling Design.

Modules in pro/e

There are three basic Pro/ENGINEER design steps from conception to completion:

Part creation

Assembly creation

Drawing creation

Each design step is treated as a separate Pro/ENGINEER mode, with its own

characteristics, file extensions, and relations with the other modes. All information

dimensions, tolerances, and relational formulasare passed from one mode to the nextbidirectionally. This means that if you change your design at any mode level, the change is

automatically reflected at all mode levels. If you plan ahead and use the associative features

correctly, you can save significant time in the design and engineering process.

Part Mode: The Dashboard and Sketcher

In Part Mode, you create part files (.prt), the separate components that are joined

together in an assembly file (.asm). Part mode lets you create and edit the features

the extrusions, cuts, blends, and roundsthat comprise each part being modeled.

Most features start with a two dimensional outline, or section. When the section is

defined, you assign a third dimension value to it in order to make it a 3D shape. You

create the 2D section in a tool called Sketcher. As the name implies, Sketcher lets

you roughly draw the section with lines, angles, or arcs, and then input the precise

dimensional values later.

You use an interface called the dashboard to create and edit 3D feature geometry.

The dashboard presents feature-specific fields for input as you switch from feature


6/28

to feature. Once a 3D feature is created, it can be edited directly in the graphics

window

Antenna tip in Sketcher and 3D mode

Assembly Mode

After you have created the parts, you create an empty assembly file for the model,

then assemble the individual parts within it, assigning the positions the parts will

occupy in the final product. You can also define exploded views to better examine or

display part relationships.

In a slightly more advanced scenario, you would start the model as an assembly and

create each part (and part file) from what is called a skeleton part. This is the key

to top-down design, where an edit to one part can automatically affect the parts to

which it is joined. You can also associate one part to another part in an ordinary

assembly using assembly relationsthese will retain associativity between dimensions as theychange.

In addition, with model analysis tools, you can measure an assembly's mass

properties and volume to determine its overall weight, center of gravity, and inertia.


7/28

Determining interference between components throughout the entire assembly is

also possible

Drawing Mode

Drawing mode lets you create finished, precise mechanical drawings of the design,

based directly on the dimensions recorded in the 3D part and assembly files. In fact,

it is not necessary to add dimensions to objects as you may have done in other

programs. Instead, in Pro/ENGINEER you selectively show and hide dimensions

that have been passed from the 3D models.

Any information objectsdimensions, notes, surface notes, geometric tolerances,

cross sections, and so onthat have been created for the 3D model can be passed to

the drawing mode. When these objects are passed from the 3D model, they remain

associated, and may be edited to affect the 3D model from within the drawing.

Basic feature/tools


8/28

Creating Files

When you use File > New to start a new file, you are prompted to select a file type,

and a subtype if one is necessary.

When you click OK, the new file opens and the default datum planes appear in the

main window. The menus and options are configured for the selected type.

Saving, Backing Up, and File Iterations

Use File > Save to save changes. Use Save a Copy to save the file to a different name.

Whenever you use the Save command, a new version of the file is created and a

numerical file extension is appended to note the version, for example

front_cover.prt.1, front_cover.prt.2, and so on. These iterations are created so you

will always have a previousversion to return to in case something fails in the current

file. When you use File > Open to open a file, the file browser displays the latest

versions without the iteration numbers.

To show version numbers in the Open dialog box, click the Commands and Settings

icon and then click All Versions from the menu. You can then open whichever

iteration you want.

To save a file to a different name, format, or location use File > Save a Copy. Unlike

a conventional Windows Save As command, Save a Copy leaves the original file

open and active after the save operation.

If you don't want to store the iterations in your working directory you can use File >

Backup to specify an alternate directory for the iterations. The first iteration in a

backup directory starts at 1, regardless of the number of iterations in the working

directory.


9/28

Deleting Files

Use File > Delete to remove files from the disk permanently. You can clear old

versions only, leaving the latest version intact, or you can clear all versions.

Use File > Delete > Old Versions to clear the directory of all but the most recent

version.

Solid Display Options

As your model becomes larger and more complex, you will switch from solid to

wireframe display to help in selection and to improve computer performance. The

two main display modes are shaded (solid) and lined. There are three types of lined

display. Each shows the outlines of the model in increased detail.

Wireframe and shaded displays

Part Design Basics

This topic introduces the elementary tools and principles of solid geometry creation

in Pro/ENGINEER. After a brief discussion of 3D datum planes and axes used to


10/28

locate solid features, you'll learn how to start solids as 2D outlines, or sections, in

Sketcher. You'll then see how to add the z-dimension to create 3D objects.

Datums, Axes, and Coordinate Systems

When you start a new part, three datum planes and a coordinate system are addedfor you. The datum planes are automatically named Front, Top, and Right. The

coordinate systemindicates the x-, y-, and z-axes. The positive z-axis isperpendicular to the front datum plane. If you orient the datums so theFront plane is flat to the screen, the z-axis is perpendicular to the screen.

Datums are points of reference in space that Pro/E uses to calculate distances.

Datums can be actual points, planes, or curves, but they have no value for thickness.

You will create and place them frequently for a variety of uses in both Part and

Assembly modes.

Like solid features, datums are added to the Model Tree as you create them. They

are named numerically by default, for example DTM1, DTM2 (for datum planes) or

PNT1, PNT2, (for datum points). You can rename them to better describe their

purpose after they are added.

Datum points and coordinate systems are similar in that they are both points either

fixed or offset from a surface or vertex. You can use datum points separately or

combine them into a patterned array that behaves as one feature. These arrays can

be saved as ASCII files and reused in other designs.

Coordinate systems are points that define an x-, y-, and z-direction. Each part that

you create is based on a coordinate system, and you may use coordinate systems

within parts or assemblies to define the direction of other components. Coordinate

systems are used, for example, in cabling connector parts to define the direction that

an autorouted wire or cable will exit the connector.


11/28

You can add datums at any time from the main menu, using Insert > Model Datum,

or you can click the datum creation toolbar buttons on the right side of the graphics

window.

To redefine datums, you can select them from the Model Tree, then right-click and

choose Edit Definition from the right mouse button shortcut menu. You can also

add datums on the fly or in the middle of other processes. Datums that you add tocreate specific features remain with the feature's section, and are not displayed in

the 3D model.

Sketcher

How to Sketch a Line

1. Click the left mouse button at the location where you want to start the line. A red

rubberband line appears, attached to the cursor.

2. Click the left mouse button at the location where you want the line to end.

Pro/ENGINEER creates a line between the two points and starts another

rubberband line.

3. Repeat Step 2 until all the lines have been created.

4. Click the middle mouse button to end line creation. The rubberband line

disappears.

How to Sketch a Circle

1. Click the middle mouse button at the desired location for the center point. A red

rubberband circle appears, centered on this point and attached to the cursor.

2. To size the circle, move the mouse away from the centerpoint.

3. To complete the circle, use the middle mouse button. Use the left mouse button to

abort the circle.

How to Sketch an Arc

1. Click the right mouse button on the endpoint of an existing entity. A red

rubberband arc appears, attached to the cursor at its other end. The arc will be

tangent to the existing entity.2. To size the arc, move the mouse away from the first pick.

3. To complete the arc, use the right mouse button. Use the middle mouse button to

abort the arc.

How to Sketch a Point


12/28

1. Choose Sketch from the SKETCHER menu and Point from the GEOMETRY

menu.

2. Pick where you want to place the point. The system displays the point.You can

add points to a sketch to make it easier to dimension section geometry. Points can be

sketched on geometry or away from

it. However, points placed off geometry are considered reference points. You canalso select points for creating splines.

When you add points to a sketch, unless their location is implicitly defined, they

must be dimensioned. A point is implicitly defined when it is placed at the end of a

line, spline, or arc, at the center of arcs and circles, or at the Intersection of two

entities.

Sketching Lines with the Line Option

You can create two types of lines: geometry lines and centerlines. Geometry lines

are used to create feature geometry. Centerlines are used to define the axis of

revolution of a revolved feature, to define a line of symmetry within a section, or tocreate construction lines. Centerlines are not used to create feature geometry.

Note: You must dimension the orientation of angled centerlines.

How to Sketch Lines With the Line Option

1. Choose Line from the GEOMETRY menu. The system displays the LINE TYPE

menu.

2. Choose Geometry or Centerline from the top portion of the menu to indicate the

type of line.

3. Choose a command from the bottom portion of the menu to indicate how you

want to create the line. The possible options are as follows: 2 PointsCreate a line by picking the start and end points. Geometry lines created

using this option are

automatically chained together.

ParallelPick an existing line to determine the direction of the new line, then pick

the start and end points. For a centerline, only a single pick is needed to determine

the parallel placement of the linePro/ENGINEER selects the ends of the

centerline to fit model or section outlines.

PerpendicularPick an existing line to determine the direction of the new line,

then pick the start and end points. For a centerline, only a single pick is needed to

determine the perpendicular placement of the linePro/ENGINEER selects the

ends of the centerline to fit model or section outlines.

TangentPick an endpoint of an arc or spline to start thenew line and determine

its direction, then pick the endpoint of the line. For a centerline, only a single pick is

needed to determine the tangent placement of thelinePro/ENGINEER selects the

ends of the centerline tofit model or section outlines.

2 TangentPick two arcs, splines, or circles to determine the direction of the new

line. Pro/ENGINEER creates the line between the selected entities, and splits the

entities at the tangency points. A 2 Tangent line created to construction entities will


13/28

not split the entity. Similarly, a 2 Tangent centerline, created as 2Tangent line

defined using two circles, will not split the circles.

Pnt/TangentPick a point anywhere in the current section, then pick an arc,

spline, or circle to which the line must be tangent. Pro/ENGINEER creates the line.

HorizontalCreate a line that is horizontal, relative to the orientation of the

section. For a geometry line, the endpoint is automatically the start point of achained vertical line. For a centerline, only a single pick is needed to determine the

vertical location of the line.

VerticalCreate a line that is vertical, relative to the orientation of the section.

For a geometry line, the endpoint is automatically the start point of a chained

horizontal line.

For a centerline, only a single pick is needed to determine the horizontal location of

the line.

Sketching a RectangleYou can create rectangles with the Rectangle option in the GEOMETRY menu.

This option allows you to create a rectangle with vertical and horizontal sides byselecting the start and end points of a diagonal.

How to Sketch a Rectangle1. Choose Rectangle from the GEOMETRY menu.

2. Select the start point by clicking with the left mouse button at the desired location

in the Sketcher window.

3. To size the rectangle, drag the endpoint of the diagonal.

4. To accept the rectangle, click the left mouse button. Click the middle mouse

button to abort the process.

The four lines are independent, as if you had sketched them separately. The lines

can be individually aligned, moved, trimmed, dimensioned, and so on.

Sketching an ArcThe following procedure explains how to create an arc with the Arc option.

How to Sketch an Arc1. Choose Arc from the GEOMETRY menu. The the ARC TYPE menu appears.

2. Choose one of the following options from the ARC TYPE menu:

Tangent EndThis is the same as creating an arc using Mouse Sketch, except you

must use the left mouse button. Pick an end of an existing entity to determine

tangency, then pick a location to place the other endpoint of the arc.

ConcentricPick an existing circle or arc as a reference then pick the start andend point of the new arc. As you create the arc, the system displays a radial line

through the center of the arc to help you align the endpoint.

3 TangentSelect three entities that the new arc will be tangent to, then create the

arc in the same direction as the reference picks.

FilletPick two entities between which to create a tangent arc. See Fillet Arcs on

page 2 - 11 for more information.

Ctr/EndsPick the center point of the arc, then pick the endpoints of the arc.


14/28

3 PointPick the endpoints of the arc, then pick a point on the arc.

Fillet Arcs

Fillets create a rounded intersection between any two entities. When a fillet is

inserted between two entities, the two entities are automatically divided at the fillettangency points. If the fillet is between two non-parallel lines, the lines are

automatically trimmed to the fillet. If the fillet is between any other entities, the

entities will be divided and the unwanted sections must be deleted manually.

You cannot create a fillet arc between the following:

Parallel lines

A centerline and another entity

Sketching CirclesYou can create two types of circles: geometry circles and construction circles.

Geometry circles are used to create feature geometry. Construction circles are used

as guides or references and are not used to create feature geometry. Like geometryentities, construction circles are displayed in cyan. However, construction

entities appear in phantom line style.

How to Sketch Circles

1. Choose Circle from the GEOMETRY menu. The system displaysthe CIRCLE

TYPE menu.

2. Choose Geometry or Construction from the top portion of themenu to determine

the circle type.

3. Choose a command from the bottom portion of the menu to indicate how you

want to create the circle.pickpick The possible options are as follows: Center/PointThis is the same as creating a circle using Mouse Sketch, except you

must use the left mouse button.

ConcentricPick a reference circle or arc, then a point on the radius of the new

circle.

3 TangentCreate a circle tangent to three reference entities.

FilletCreate a circle tangent to two specified entities.

3 PointPick three points that lie on the circle.

Datum PlanesYou can use datum planes to create a reference on a part where one does not

already exist. For example, you can sketch or place features on a datum plane when

there is no appropriate planar surface. You can also dimension to a datum plane as

if it were an edge. When you are constructing an assembly, you can use datums with

assembly commands.

Datum Plane Colors and Names


15/28

By default, datum planes have two sides: yellow and red. You use the colors when

you assembl components, orient views, and sketch references. Pro/ENGINEER

displays datum planes as red or yellow, depending on which side is facing the

screen. When you create datum planes, the system assigns them names in sequential

order (DTM1, DTM2, and so on). You can change the names of the datum planes

using the Setup option in the Part menu and the Name option in the PART SETUPmenu.

Selecting Datum PlanesTo select a datum plane, you can pick on its name, or select one of its boundaries.

The visual boundaries of the datums sometimes get in the way of selecting surfaces

or edges of the model. If this happens, use Query Sel, or set the configuration file

option select_on_dtm_edges to sketcher_only so the visual edges of the datum

are selectable only when you dimension sketched sections.

Creating Datum Planes On-the-Fly

In the process of feature creation, the system lets you create a datum plane on-the-fly using the Mak Datum option in the Setup Plane menu. Consider the following

rules about the datum planes created on-the-fly:

Datum planes that you create during feature creation are internal to and belong to

that feature.3 - 4 Part Modeling Users Guide

Datum planes on-the fly become invisible after you create the feature. Any

associated dimensions positioning the datum plane are included with those of the

feature. This gives you more choices for varying dimensions when you create a

feature pattern

Datum planes created on-the-fly cannot be referenced by other features.

When you use Copy/Mirror to copy features and use datum planes on-the-fly as

the mirror plane, this datum plane stays visible because it can be referenced bymore than one feature.

Creating a Protrusion

The following procedure explains how to create a protrusion.

How to Create a Protrusion1. Choose Feature > Create > Solid > Protrusion.

2. Specify a method of adding material by choosing an option from the SOLID

OPTS menu. The options are: ExtrudeCreate a feature by extruding its section.

RevolveCreate a feature by revolving its section.

SweepCreate a feature by sweeping a section along a trajectory.

BlendCreate a feature by blending multiple sections.

Use QuiltCreate a feature by adding material to a quilt.

AdvancedCreate features using advanced feature forms.

3. Select an option from the lower portion of the SOLID OPTS menu:


16/28

Solid(Default) Create a feature as solid.

ThinCreate a thin feature by specifying the features thickness as a parameter.

Choose Done from the SOLID OPTS menu.

4. Define the feature as prompted by the system.

Different Types of Protrusions

Specifying the Depth

When you define the Depth attribute of a feature (for example, a protrusion, cut,

slot, hole, or surface feature), the SPEC TO (or SPEC FROM) menu appears with

the following options:


17/28

BlindEnter a dimension for the feature depth. You can then control the feature

depth by changing the depth dimension.

2 Side BlindFor a feature defined as Both Sides, enter a separate depth value for

each side with respect to the sketching plane.

Thru NextTerminate the feature at the next part surface.

Thru AllThe new feature intersects all surfaces. Thru UntilExtend the feature until the intersection with the specified surface.

Pnt/VtxSpecify the depth up to a plane parallel to the sketching plane, and

passing through the selected datum point or vertex.

UpTo CurveSpecify the depth up to a plane parallel to the sketching plane, and

passing through the selected edge, axis, or datum curve.

UpTo SurfaceSpecify the depth up to a selected surface.

Sweeps, Blends, and Advanced Features

SweepA sweep is created by sketching or selecting a trajectory and then sketching a

section to follow along it. You can create more advanced sweeps using the Advanced

option.

How to Create a Swept Feature

1. Use the command sequence Feature, Create, Solid,Protrusion.

2. Choose Sweep and Done from the SOLID OPTS menu.

3. Pro/ENGINEER displays the feature creation dialog box for sweeps.

4. Sketch or select the trajectory using a SWEEP TRAJ menu option. The trajectory

can be open or closed. The options are as follows: Sketch TrajSketch the sweep trajectory using Sketcher mode.

Select TrajSelect a chain of existing curves or edges as the sweep trajectory. The

CHAIN menu allows you to select the desired trajectory (see Chain Processing on

page 3 - 33).

5. If the trajectory lies in more than one surface, such as a trajectory defined by a

datum curve created using Intr. Surfs, the system prompts you to select a normal

surface for the sweep cross section. Pro/ENGINEER orients the Y-axis of the cross

section to be normal to this surface along the trajectory.

6. Create or retrieve the section to be swept along the trajectory and dimension it

relative to the crosshairs displayed on the trajectory. Choose Done.

7. If the trajectory is open (the start and end points of the trajectory do not touch(see the illustration Free and Merged Ends) and you are creating a solid sweep,

choose an option from the ATTRIBUTES menu, then Done. The possible options

are as follows:

Merge EndsMerge the ends of the sweep, if possible, into the adjacent solid. To

do this, the sweep endpoint must be attached to part geometry.

Free EndsDo not attach the sweep end to adjacent geometry.


18/28

BlendA blended feature consists of a series of at least two planar sections that

Pro/ENGINEER joins together at their edges with transitional surfaces to form a

continuous feature. Blends with parallel sections can be created in basic

Pro/ENGINEER, but the Pro/FEATURE and Pro/SURFACE modules are requiredto create blends from non-parallel sections.

How to Create a Blend1. Use the command sequence Feature, Create, Solid, Protrusion.

2. Choose Blend and Solid or Thin from the SOLID OPTS menu, then Done.

3. Choose options from the BLEND OPTS menu, then Done. The BLEND OPTS

menu options are as follows:

ParallelAll blend sections lie on parallel planes in one section sketch

RotationalThe blend sections are rotated about the Y-axis, up to a maximum of

120 . Each section is sketched individually and aligned using the coordinate system

of the section. GeneralThe sections of a general blend can be rotated about and translated

along the X-, Y-, and Z-axes. Each section is sketched individually and aligned using

the coordinate system of the section.

Regular SecThe feature will use the sketching plane.

Project SecThe feature will use the projection of the section on the selected

surface. This is used for parallel blends only

Select SecSelect section entities. This option is not available for parallel blends.

Sketch SecSketch section entities.

Creating a Variable Section Sweep

The following procedure explains how to create a variable section

sweep.

How to Create a Variable Section Sweep1. Choose Advanced and Done from the SOLID OPTS or SRF OPTS menu. The

system displays the ADV FEAT OPT menu.

2. Choose Var Sec Swp, then Done from the ADV FEAT OP menu. Pro/ENGINEER

displays the feature creation dialog box and the VAR SEC SWP menu.

3. Choose an option from the SWEEP OPTS menu, then choose Done. The options

are as follows:

feature also follows these trajectories as it travels along the origin. The trajectories

can be accessed by selecting the Trajectories element in the dialog box. You can

remove a trajectory by choosing Remove Traj from the VAR SEC SWP menu.

9. Choose Done to complete the trajectory definitions.10. Sketch the sweep section. The section can be dimensioned to known points (to

the points of intersection of the longitudinal curves with the sketching plane). The

section remains aligned and dimensioned to the point as it sweeps along the

curve.Use relations to create a meaningful parametric section.

11. Choose Done to exit Sketcher.

12. Click OK in the dialog box.

Helical Sweep

You create a helical sweep by sweeping a section along a helical trajectory. The

trajectory is defined by both theprofile of the surface of revolution (which defines

the distance from the section origin of the helical feature to its axis of revolution)

and thepitch (the distance between coils). The trajectory and the surface of

revolution are construction tools that do not appear in the resulting geometry. See

the following illustration Types of Helical Sweep Features for an example of the

different types of helical sweep features.

The Helical Swp option in the ADV FEAT OPT menu is available for both solid and

surface features. Use the following ATTRIBUTES menu options in mutually

exclusive pairs to define the helical sweep feature:

ConstantThe pitch is constant. VariableThe pitch is variable and defined by a graph.

Thru AxisThe cross section lies in a plane that passes through the axis of

revolution.

Norm To TrajThe cross section is oriented normal to the trajectory (or surface

of revolution).

Right HandedThe trajectory is defined using the righthand ule.

Left HandedThe trajectory is defined using the left-hand.

Types of Helical Sweep Features

How to Create a Helical Sweep with Constant Pitch Value1. Choose Advanced and Done from the SOLID OPTS menu, then elical Swp and

Done. The system displays the feature reation dialog box.

2. Define the feature by selecting from the ATTRIBUTES menu, hen choose Done.

3. Pro/ENGINEER places you in Sketcher mode. Sketch the rofile of the surface of

revolution. Specify the sketching plane nd its orientation, and the axis of revolution.

Advanced Features

4. Sketch, dimension, and regenerate the profile Follow these rules:

The sketched entities must form an open loop. You must sketch a centerline to define the axis of revolution

If you chose Norm To Traj, the profile entities must be angent to each other

The profile entities must not have a tangent that is normal o the centerline at any

point.

The profile starting point defines the sweep trajectory tarting point. You can

modify the starting point using the ptions Sec Tools and Start Point.

5. When you have finished sketching the section, choose Donefrom the SKETCHER

menu.

6. Enter the pitch value (the distance between the coils).

7. For a surface feature, specify if the feature will have closed oropen ends by

selecting Open Ends or Capped Ends from theSURF END menu (see Open and

Closed Blends on page 6 - 16),then Done.8. Pro/ENGINEER places you in Sketcher mode to sketch thecross section that will

Drawing module

Placing General Views and Projection Views

The first view you place will be a type called a general view. You can regard a

general view as a parent view because its orientation and scale can be adjusted, and

these properties determine the look of any projected views derived from it.

Projections (projected views) are views derived from the general view, which show

alternate faces of the general view. Using projections you can quickly dimensionevery surface of a 3D object without repeating a dimension. Each projection view

exists in either a horizontal or vertical projection channel to the right, left, above, or

below the general view. Projection views are automatically aligned with the general

view within their projection channels. By default, they can only be moved within the

channels they occupy.

Creating a New Drawing File

The finished drawing will have an exploded view of the assembly on the first page,

with a bill of materials and BOM balloons calling out the parts. However, becausethese are the more complex elements of the drawing, youll add them last. First

youll add a view of the antenna part to the drawing. Later in the tutorial youll add

the assembly view and the BOM. Start the new drawing file:

1.Click File > New and select Drawing from the New dialog box. Enter a name for

the drawing and clear the Use default template check box. Click OK. The New

Drawing dialog box opens.

2.In the Default Model field, use the Browse button to enter the antenna part file.

3.In Specify Template, click Empty with Format. Click the Browse button to go to

the default system formats directory. (This is usually part of the default installationsetup for Pro/ENGINEER).

4.Select the C size sheet (c.frm) and click Open, and then click OK in the New

Drawing dialog box. A new blank sheet opens, with the format outlines.

Now you will add a general view and a projection to the sheet, orient the view,

change the views properties and show dimensions.

1.Click Insert > Drawing View > General. You are prompted to select a center point

for the drawing view. Click the center-right area of the sheet.

2.The view is placed and the Drawing View dialog box opens, showing all the saved

3D orientations. In the dialog box, under Model View Names, select Front from thelist. Click Apply.

3.Under Orientation Method, select Angles. Enter 270 for the angle value and click

Apply. The view reorients to the horizontal, with the tip pointing to the right. Click

OK in the dialog box to close it.

Add the Detailed View

Now youll add the detailed view. This involves a series of prompts that define the

elements shown in the following figure.

1.Click Insert > Drawing View > Detailed. Click along the outline of the tip in

the general view. At the spline prompt, use the mouse to click-draw a circle to

enclose the detail to be enlarged. Middle-click when the circle is almost complete.

A circle is added around the tip.


25/28

2.Define the note and leader location by clicking anywhere near the circle. The note

is added at the selected point (it can be dragged to another position at any time).

3.Click in the upper middle of the sheet, and the detailed view is added. Drag it inany direction to redefine its position.

4.Right-click the detailed view, and then choose Properties from the shortcut menu.

Choose Scale from the Categories list and enter a value of 9 for the custom scale,

and then click OK.

Create the Table

A table is a series of cells of a given height and width. You can enter "dumb" text

into the cells, for example as a column heading. The first step in creating the BOM isto define the table.

1.Click Table > Insert > Table. You are prompted to locate the upper-left corner

of the table. Click at a point where the upper-left corner would be on the sheet.

A scale of numbers appears horizontally from the clicked point.

2.Click around the number 5 or 6. The width of the first column is defined, and

the scale moves to the right.

3.Click the scale again to define another column width about twice as long.When you have defined this column, click the middle mouse button. The


26/28

horizontal scale is replace escending horizontal scale. Now youll define the

number of rows.

4.Youll need two rows to start, one for the column headings and one for the

parameters. Click twice down the scale to create the two rows and middle-click to

complete the cells. The table should look like this.

Add BOM Parameters

1.Double-click the left side cell of the repeat region. Because it is now a repeat

region, the Report Symbol menu opens by default. These are the top-level prefixes,

denoting the modules for which reports may be generated. This menu lets you

assemble a report parameter string by punching down through eligible

parameters.

2.Click rpt..., then index. The cell now contains the heading rpt.index. Now double-

click the lower-right cell and then asm. > mbr. > name on the Report Symbol menu.

The assembly member name parameter you have just created is entered into thecell.

3.Click Table > Repeat Region > Update Tables > Done. The table is expanded to

show the information as defined by the parameters.

Show BOM Balloons

BOM balloons are the finishing touch to the first sheet. First youll assign an

existing repeat region as a BOM balloon region. Then all you need to do is choose to

show the balloons, and arrange them as you want them.

1.Click Table > BOM Balloons. In the Menu Manager, choose Set Region. You areprompted to select a region in the table. Because the table has only one region, click

anywhere in the table to select the region. Once the region has been selected, the rest

of the Menu Manager items are available.

2.Now click Create Balloon on the Menu Manager under BOM BALLOONS. You

are prompted to select the view in which to show them. Click the general view, and

then Done on the Menu Manager. The BOM balloons are added to the view.

3.You can right-click the view and choose Cleanup BOM Balloons from the shortcut

menu to modify the positions of all balloons. To fine-tune the layout, select and drag

each balloon separately to a new location, or right-click a specific balloon and

choose Edit Attachment to select a new attachment edge on the object.
