MagiCAD Heating&Piping and Ventilation version 2011.11


6 1. Project

1. Project


1.1. Creating the project 7

1.1. Creating the project After you have made initial procedures, you can create the MagiCAD project. Initial procedures have beenexplained in other document. C:\Project1 directory is used in this example.

If Add drawing to the model drawing list option is active, drawing will be added to the Model drawings list. Youcan add connection nodes between the drawings in the list and those drawings can also be added to the bill ofmaterial. Missing drawings can be added in the Project dialog (Project -> Model Drawings).

Give the name for the project. 3 project files will be created: *.epj, *.qpd and *.linIf you click the ... button beside the Location field, the following dialog opens:

Here you can see all the possible places, where you can save the project files. Select the folder.


8 1.1. Creating the project

Select MagiCAD template. You can use templates for example from MagiCAD HPV\Templates folder. Template isprefilled project file, which contains some systems, devices, components, dimension texts, sizing criterias, duct/pipe series etc.Note! You can also use old projects as a template!


Location of the project files 9

Location of the project files Project files (*.epj, *.qpd, *.lin) and MagiCAD drawings can be added to the same folder or you can devide themdifferent ways. Here is one example:

The best place for the project files is the main folder of the project. You can have several subfolders under themain folder. You can divide the drawings e.g. so that all the system goups are in their own folders. If the project files are saved to the main folder of the project, all the drawings in main folder or its subfolders andtheir subfolders can be connected to the MagiCAD project.


10 Storey list, active storey, storey origin

Storey list, active storey, storey origin After you have created the project, Project Management dialog is opened. Now you still need to “tell” whichstorey the active drawing is. First you need to create the Storeys list. There you define all the storeys in thebuilding and how the storeys are located relatively to each others.

Select the group that you want to edit. With the Install storey origin function you can install the MagiCAD origin point. MagiCAD needs its own origin, sothat it knows how the storeys are located relatively each others. With the Active storey function you can select the active storey for the active building.Edit the existing information or add/copy new products and information by right-clicking in the right window pane.After right-click you can choose the operation from the popup menu.


Storeys 11

Storeys

Select the storey from the list and choose an option from for the pop-up menu.

Import - import the storey list from MagiCAD Room project. If you edit the storey, the following dialog opens:

ID - an unique identifier for the storey. It is not possible to change the ID afterwards.x, y and z – define the location of the storey relative to the storey origin. This is the left lower corner. Thisdefines how the storeys are located according to each others.Install the storey origin to the point which is the same in all storeys. Good points are for example the corner of thebuilding, crossing point of module lines. Sometimes it is good to draw a helping line for example from the cornerof the elevator.a and b – Define the size of the building/drawing area. A value is the size in x-direction and b value is the size iny-direction.h – Room height. If you use linetypes according to objects height level, this value is one height level where thelinetype changes.You can add some notes to the text fields.


12 Storeys


Active storey 13

Active storey After the storey list is ready, you still need to “tell” which storey the active drawing is. Storey list can be edited afterwards.


14 Install storey origin

Install storey origin MagiCAD needs its own origin point to be able to understand the location of all the storeys. Because of this, allthe ducts and pipes are in right place when they are taken from storey to other storey (with connection node –function).

Give the coordinates if you already know them. Show the origin point for MagiCAD. Start the function, show the origin point and then the direction of x-axis. Quite often the origin point is good to install to the lower left corner of the building. Good point is also crossingpoint of module lines. Sometimes it is needed to draw some helping line from some constant point of the building– for example from the corner of the elevator. When installing the origin point, it is good to zoom the corner point closer (zoom window). Use also AutoCAD’sSnap Intersection–function (you can find it for example by pushing Ctrl-button down and taking the right click.Select the corner point and show the direction of the x-axis after this. Use AutoCAD’s ORTHO (F8) value on to besure that the direction of x-axis is straight.

Project Management dialog is reopened after installing the storey origin. If it is ok, you can close the ProjectManagement dialog and start to draw. Alternatively you can reinstall the storey origin, if it went to a wrong placeor position.


Conclusion 15

Conclusion Before you can start to draw with MagiCAD, you need to connect the drawing to the existing project or createthe new project. And in both cases you need to select the active storey for the drawing and also install theMagiCAD’s storey origin.


16 1.2. Creating systems in MagiCAD

1.2. Creating systems in MagiCAD Every MagiCAD object belongs to some system. There can be hundreds of systems in same project, if needed.All the systems are located in the Project Management dialog.

Select the system and take a right click in the window in right. A popup menu opens and you can add, edit ordelete systems.

1.7. Sizing methods 41

1.7. Sizing methods SettingsYou can select the wanted sizing method for each ventilation-, heating/cooling –and water system. It is alsopossible to create new sizing methods.When you start to create -or edit sizing methods, you need to select the sizing method. Sizing methods arelocated in Project dialog under each system group (Project -> Ducts/Pipes -> Sizing methods).

Sizing methods for ventilation

Add the new criteria with Ins button and edit the existing criteria with double-click.Dekv-max –defines the maximum diameter that v-max and dp-max are used with


42 1.7. Sizing methods

v-max [m/s] – maximum velocity. When the velocity is reached, MagiCAD takes the next size.dp-max [Pa/m] – maximum friction loss. When the pressure is reached, MagiCAD takes the next size.In this example the ducts are sized according to velocity – that’s why the dp-max is set so high that it is neverexceeded.With this sizing method the sizing goes through all the duct sizes and change the size if the velocity exceeds the4 m/s. This is used until ø160 duct size is reached. After that MagiCAD allows 5 m/s to the duct size ø315. Andso on.Note! The values have to be in right order in the list. It is also allowed to use both velocity and friction loss insame method. Sizing methods for heating, cooling and special systems

46 1.9. Absorption material (inner insulation)

1.9. Absorption material (inner insulation) It is possible to define an absorption material series in project management. Absorption material is the insulationwhich is inside of the duct. SettingsIt is possible to create new absorption material in the Project dialog (Project -> Ducts -> Absorptionmaterial series)

ID – makes all insulation series unique. It is not possible to change it afterwards.UserCode – identification for the series.Description - description for the series. This is shown in the lists where you select the systems.Thickness – Define the thickness for insulation. InstallationAbsorption material is added to ducts by using the Change Properties functions.


1.9. Absorption material (inner insulation) 47

Calculation with absorption materialPressure drop and sound calculation take absorption material into consideration.

• Calculations which calculate the velocity (e.g. flow summation) take the absorption material intoconsideration

• Duct sizing checks the velocity and roughness caused by the absorption material

• Pressure drop calculation takes the absorption material into consideration

• Pressure drop calculation of outlets calculates the branches by using the speed according to the inner

diameter with an absorption material. The frictional resistance between the outlets also takes theabsorption material into account.

• Sound calculation takes the smaller surface area and higher speed into account (ducts and fittings).


48 1.9. Absorption material (inner insulation)

• The attenuation of ducts is calculated according to SMACNA definitions.

• The attenuation of ducts is calculated according to SMACNA definitions. Note! SMACNA does not have

the reasonable values for circular bends and rectangular bends with rounded shape, so in these cases theattenuation is always calculated without absorption material.

• The attenuation calculation of distribution box has been changed according to SMACNA definitions.

However, SMACNA definitions cover only a chamber with one inlet and one outlet at the opposite side.Therefore MagiCAD uses its own formula for calculating the sound attenuation of separated ducts.Inaddition, SMACNA does not include a formula for the low octave bands of a chamber without attenuation(the basic formula has a boundary frequency, under which the formula is not valid), so in this case the lowoctave bands will only have the distribution attenuation.


1.10. Update Drawing Data 49

1.10. Update Drawing Data

With this function ( ) you can update the information from project to drawing. This is needed if information ischanged in the Project dialog. Almost every type of information can be changed and they can be updated to drawings - for example, symbols,product information, layer names, colors etc.

54 2.1. Drawing the ducts

2.1. Drawing the ductsGeneralStart to draw duct with Duct –button . If the command is used first time in this MagiCAD session the Designoptions –dialog is opened automatically. Later it can be opened by taking the Options from the PopUp menu(right click). Drawing optionsMagiCAD have 2 different "list" for drawing options. The other one is available before any part of duct have beendrawn -> start the duct drawing and take a right click when PopUp menu opens.

More options will be available after drawing a piece of duct. EditingIt is possible to edit all the values afterwards. For example Duct serie -and size, insulation serie, status, lockstatus and branch types can be added/changed afterwards with Change Properties function.


Design Options 55

Design Options

Duct options• Series – select the wanted duct serie• Size – select the duct size. If the system will be sized with MagiCAD, then it doesn’t matter which size is

used. It is however recommended to use as right sizes as possible because then it is easier to pre-makecrossings and predict the space requirements.

• Locked – it is also possible to lock the duct sizes. If the size is locked then MagiCAD’s sizing does notchange the duct size.

• Swapped – this option change the rectangular ducts width and height to opposite. For example 300x100 swapped 100x300.

InsulationSelect the insulation serie if needed (defined in Project -dialog).

Flange seriesSelect the flanges if needed (defined in Project -dialog). Flanges are shown with rectangular ducts.

StatusIt is also possible to select the status for the ducts. Status can be for example new, to be removed, existing

etc.

RoutingSelect the routing method:

Smart – MagiCAD always use standard parts (for example bends)Direct – it is possible to draw with non-standard parts


56 Design Options

Height difference in branchSelect the bend for the main duct – branch connections. This bend is used only when the drawing direction

is toward the main duct and if the ducts are in different height levels.Example: 30 deg is active and the duct is drawn from air device to main duct. Air device is in lower height levelthan main duct. When the branch duct is connected to main duct, 30 degree angle is used.

Alignment optionIt is possible to draw the ducts with different alignments. If the duct is drawn by using the alignment points,

width-, height -or both values are locked:

Bend -and reduction typesSelect the bend -and reduction type for circular –and rectangular ducts.

Branch typeSelect the branch types for duct-duct connections.

• Use outlets that break the duct as T-branches - if this is active, outlet breaks the duct and

in this case sizing is able to change the size of the main duct as well.Note: This option can be changed with Change Properties!

• Allow different connection sizes - With this option MagiCAD does not create a reductionto T-branches, if the duct size is changed. Instead of reduction, MagiCAD change the size of T-branchconnections.

Automatically select products (while drawing)If Automatically select products (while drawing) is selected, MagiCAD automatically select real products

if possible (real product has to be selected to duct series). If the box is unselected, MagiCAD uses genericproducts. If Show warning if product not found is selected, MagiCAD gives a warning message (in command line) ifsuitable product is not found.


Design Options 57

Automatical flexible duct selectionSelect the settings for automatic flexible duct connection.

If this setting is active, MagiCAD will convert the connection duct automatically to flexible duct according to thesettings.Note! Connection duct can be changed afterwards with Change Properties.

2.6. Production model 93

2.6. Production model In MagiCAD 2009.11 and earlier MagiCAD always used generic products. Now the user can select whetherMagiCAD uses real products instead of generic ones. Real products have the exact dimensions from the manufacturer.


94 Selecting real products to the project

Selecting real products to the project MagiCAD Project Management now includes a new selection for real product fittings (Project Management -> Ducts -> Parts -> Fittings). Different parts (bends, t-branch etc.) can be selected to project just likeany other component. Products that are already selected to the project appear in the window in right side. Right-click the mouse in the window and select the desired option from the popup menu.

Properties... – Shows the information of the productEdit – Editing the product informationDelete – Delete the selected product from the projectSelect products to project… - Select new fittings from manufacturer`s databasesSelect non-geometry products to project – Select generic products, whose dimensions do not comefrom manufacturer. These parts were used in older MagiCAD versions. When you select the Edit option, the following dialog opens:

Usercode - Identification code for product. It is shown in product lists and bill of material list. It can also be usedin dimension texts.Product variables - value can be used in layer name with layer variable {PV}. P1-P5 are for extrainformation.National code – the possible standard code can be set to this field.Product – Product code of the selected product.


Selecting real products to the project 95

Object ID format - Devices can have an automatic device ID. It nothing is selected, then this value can beset manually for devices. Object ID settings can be defined in Project -> Variable sets -> object IDformats.


96 Selecting products to duct series

Selecting products to duct series Now when the wanted products have been selected for the project, they need to be added to duct series beforeuse. They can be added to selected duct series or maybe better way is to do own duct series for the real parts.NOTE! MagiCAD templates include Lindab Safe series which includes new products.

If Show all part types option is selected, Available products list shows all products that are selected from theproject. Uncheck the box and it is possible to select specific product type to available products list (duct, bend, t-branch etc.) Available products list show the selected products as selected from the filter.


Selecting products to duct series 97

Select the products which will be included to duct series from the list and click the right arrow button to add themto the Selected products list (or double-click the part). To remove already selected products from the Selectedproducts list, click the left arrow button. Selected products list shows products that are already selected to duct series. With Up and Down buttons theorder can be changed. MagiCAD always uses the first available product.


98 Using the new products

Using the new products Products are ready to use after they have been selected to duct series. New products can be selected with twodifferent ways, automatically while drawing or afterwards with Change generic objects to products function. Selecting a product while drawingTo select product while drawing can be selected from the Design Options dialog. Design Options starts with

Duct function ( ).

Select the duct series which includes the new products..The way to get MagiCAD uses the real product is this new product selection. Select Automatically select products(while drawing) if you want to use real products. If it is not selected, MagiCAD uses generic object (as previousversions).If Show warning if product not found is selected, MAgiCAD gives a warning message if suitable product cannotbe found. Draw ducts like before, and MagiCAD uses the real products (if suitable products are found).


Using the new products 99

Selecting products afterwardsProducts can be selected to ductwork also afterwards with Change generic objects to products function ( )which opens the Product Selection dialog.

Select the System Group. Real products can be selected only for ductworks.Select whether change the products to specific branch or the whole System from the Range field.System(s) which product will be changed can be selected from the System list.


100 Using the new products

Changing real products back to genericIf real products need to be change back to generic products, Change products to generic objects function

( ) should be used. It works exactly the same way as Change generic objects to products function.

And it can be moved by pushing the scrollbutton down.Define the settings for the big preview picture.


Rectangular ducts and flanges 105

Rectangular ducts and flanges MagiCAD automatically creates the flanges between duct and fittings when using real rectangular products.Flanges have a fixed size (thickness 20mm and height 20mm).

Flanges can be turned on/off from Viewport Preferences.

Note! MagiCAD is able to show the flanges in shaded views only if the setting is saved to project/drawing defaults(Viewport Preferences --> Save as project/drawing defaults). New layer settings are specified for the flanges (Connection Accessories).


106 Female connection

Female connection MagiCAD can create a female connection between two fittings. Suitable product for this is for example MF (fromLindab). MF is added between two fittings if 2xFit-on length + Extra duct length is exactly the same than thelength of the product.

For example the MF has lenght 95mm for the duct sizes ø63-ø200. In this case the Fit-on length need to be40mm and Extra duct length 15mm --> 40+40+15=95Note: This product need to be before the duct in a priority list of duct series.


Install Any Product 107

Install Any ProductInstall Any Product function ( ) can be used for installing special products. These kind of products are Y-branches, S-bends and bends with cleaning branch. In the future it is possible to install any product which is selected to project, with this function.

the same time ( .)If the command is used first time in this MagiCAD session the Pipe options dialog is opened automatically. Laterit can be opened by taking the Options from the popup menu (right click).

Series – select the pipe seriesSize – select the pipe size. If the system will be sized with MagiCAD, then it doesn’t matter which size is used.It is however recommended to use as right sizes as possible because then it is easier to pre-make crossings andpredict the space requirements.Locked – it is also possible to lock the pipe sizes. If the size is locked then MagiCAD’s sizing does not changethe pipe size.Insulation – Select the insulation series if needed. Select the pipe positioning from the cursor (supply) pipe.Distance – define the distance between the pipes If you want to avoid the crossings between branched and main pipes, you can define the automatic heightdifference in branch.Available angle options are 90° and 45°.Note! if the dH in branch value is negative, pipes goes downward.


114 3.1. Heating, cooling and special system pipes

It is also possible to select the status for the pipes. Status can be for example new, to be removed, existing etc. It is possible to define the radius for flexible pipes.Do not use – MagiCAD uses the R/D value which is defined in pipe seriesUse – if this is active, define the radius to the field. Then MagiCAD always use this radius. Select the routing method:Smart – MagiCAD always use standard parts (for example bends)Direct – it is possible to draw with non-standard parts Select how the pipes are located after the height difference. Cursor (supply) pipe stays in the height level whichwas given.Smart – MagiCAD always stretch the pipes so that they are nor crossing.

Top (cursor pipe below) – MagiCAD always keep the cursor (supply) pipe below the other pipe.

Bottom (cursor pipe above) – MagiCAD always keep the cursor (supply) pipe below the other pipe.

Manual – MagiCAD always use the settings defined in Pipe positioning from cursor pipe.



Note! Pipe series and size, insulation series, status, lock status and branch types can be added/changedafterwards with Change Properties function. Drawing the pipe(s)After the settings are ok, start to draw the pipes. You can connect to the existing pipes, radiator, cooling beametc. and then continue to draw pipes. Or you can start to draw pipes from the empty place. In this situation clickthe place where you want to draw the pipes. The Heat pipe positions dialog opens.

Select the system for the pipes.Select the height level where you want to draw pipes. It is possible to give the height level to the bottom, center ortop level of the pipe. MagiCAD then calculates the other values according to pipe size. It is also possible to copy the height level from the existing MagiCAD/AutoCAD object.Top of – MagiCAD takes the height level from the top of the selected object. This value is put to the Bottomlevel field. Then object goes over the selected objectCenter of – MagiCAD takes the height level from the center of the selected object. This value is put to theCenter field. In this case the pipe goes to the same height level with the selected objectTop of – MagiCAD takes the height level from the bottom of the selected object. This value is put to the Bottomlevel field. Then object goes under the selected object. After the suitable system and height level are selected, start to draw pipe.



Draw the pipes from point to point. Bends and T-branches are created automatically when drawing.If you want to get the pipes shorter, just draw them backward. Or if you want to go back “over” the bend/branchtake a right click and select Back option from the popup menu.Finish the drawing with enter or esc button. If you connect the pipes to the radiator or to other pipes, thecommand ends. Drawing optionsWhen the pipe is drawn, all the drawing options are shown in AutoCAD’s command line.

They can also be used from the popup menu, which appears with right click.

noConnect – if this is selected, then pipes can’t be connected to any object. This option is needed for examplein the situations where are many pipes very close each others.Angle – choose the angle to pipesZ – height difference changes are made by using this option.Options – Options dialog is opened and all the settings can be changed



Back – pipe goes back to the previous bend/branchPlug – MagiCAD add the plug to the end of the pipe.connection Node – this function add the connection node to the end of the pipe. It means that is is possible tocontinue to draw the pipe from the other storey (other dwg). All the technical data is transferred. More informationin other chapter.Valve – add valves to pipes. MagiCAD ask to install valve to supply pipe first and after that to return pipe. If only one pipe (supply or return) is drawn, then there are more options

Special connection – you can connect two open ends together with this function. Then you have possibilityto see the results with the standard angles or you can also create the special connection with non-standardangles.

smarT <> direcT – you can switch between smart and direct routing. This is the same option than in theOptions dialog.coMponent – add the component to the pipe Height difference changesHeight difference changes are always made with the Z option.



Select the height level where you want to take the pipe.It is also possible to copy the height level from the existing MagiCAD/AutoCAD object.Top of – MagiCAD takes the height level from the top of the selected object.Center of – MagiCAD takes the height level from the center of the selected object.Top of – MagiCAD takes the height level from the bottom of the selected object. Select the angle for the height difference.If the angle is some other than 90°, MagiCAD asks to show the direction for the height differenceFree angle – this active only with 1-pipe drawing. Show the end point (the point where the height level is theone you have given in Heights field). MagiCAD then chooses the angle which takes the pipe to the desired heightlevel.

Tips and tricksWhen you continue to draw the pipe, you can do it in two ways: you can select the command and then connect tothe pipe or device or you can first select the pipe or device and then start the drawing from the + grip.

Start the command and connect to the pipe or device and draw.



If you draw 2 pipes at the same time, the easiest way to connect to other 2 pipes is so that those both pipes fitsinside of the selection circle.If the drawing is zoomed so close that the pipes does not fit inside of selection circle, then you need to show thesupply pipe first and the return pipe after that. MagiCAD shows the instructions in commandline. Select the pipe, click the + mark and draw.

If you select the + grip from the middle of the pipe, MagiCAD starts the pipe command and then it is possible toconnect to any place.

If the command does not start from the + grip, turn off AutoCAD’s dynamic input ( ).

Extra options in 1-pipe drawingThere are extra options if only cold or hot water pipe is drawn. Hot water jointHot water joint is meant to use in the situations where the cold water is warmed up (heat exchanger). Draw coldpipe and select hotwaterJoint from the popup menu.



After the hot water joint is selected, MagiCAD adds a piece of hot water pipe. Then hot water pipe can be drawnfrom there.Note! MagiCAD’s Substation unit is better for this purpose! This is just a fast way to make a connection betweencold and hot water pipe. Return jointReturn joint is meant to use in the situation where the hot water turns back towards to heat exchanger (hot waterbecomes the circulation water).

Define the power for the circulation water. The flow is calculated according to the power.

After the return joint is selected and power defined, MagiCAD adds a piece of circulation water pipe. Thencirculation water pipe can be drawn from there.



Note! Some radiator or zone valve is needed in circulation water pipe, otherwise MagiCAD cannot get the systemin balance. Tips and tricksWhen you continue to draw the pipe, you can do it in two ways: you can select the command and then connect tothe pipe or device or you can first select the pipe or device and then start the drawing from the + grip.

Direction – It is recommended to rotate the radiator to correct direction before installation. It can, however, berotated afterwards with AutoCAD’s rotate function.Options – The Options dialog is opened and all the settings can be changed. Installing the radiatorInstall the radiator by clicking the desired place. The Device Height Position dialog opens.

Select the height level where you want to install the radiator. It is possible to give the height level to the top andbottom level of the radiator.Height level can be copied from some other object (Show reference part).In the Description field you can give extra information for the radiator. This value can be used in dimension textsor it can also be selected to MagiCAD Export list.


140 Installing the radiator

It is possible to select the status for the radiator. Status can be for example new, to be removed, existing etc. Itcan be defined / changed afterwards.

Pipe connects to the radiatorAfter the radiators are installed to the drawing, pipe connections can be made. There are different ways to makethe connections. Starting to draw pipes from the radiator

The pipes go to the height level of the connection pipes.



Connecting pipes to the radiator Situation 1: Pipes are connected directly from the main pipes to the radiator (Connect - Connect).Start 2-pipe drawing. Connect to the pipes and then connect to the radiator.

MagiCAD makes the connection so that it first takes the pipes to the same x/y level with radiator, then thepipes goes downward and makes the connections so that the pipes are in the same height level with the pipeconnection points. Situation 2: Pipes are drawn a little bit from the main pipes and after that connected to the radiator.Start 2-pipe drawing. Connect to the main pipes and then draw a piece of pipes. Supply pipe has to be in rightside in this case – then there will not be any crossings near by radiator. Connect to the radiator after this.



MagiCAD makes the connection so that it first takes the pipes to the same x/y level with radiator, then the pipesgoes downward close to floor. Then MagiCAD makes the connections so that the pipes go near radiator andconnect the pipes.Tip (also applies to situation 3): If there are many radiators in the same line and the pipes should go below theradiators, it is profitable to connect the pipe to the last radiator and then connect the other radiators.

Start 2-pipe drawing. Connect to the main pipes and then draw a piece of pipes. Connect to the last radiator afterthis.Pipes go below radiators and then makes the connection to the last radiator. Connect the other radiators afterthis.

Start 2-pipe drawing. Connect to the radiator and then connect to the pipes which go below radiator. MagiCADmakes the connection.



Situation 3: Connection from the riser pipes so that the pipe goes below the radiators.

Connect to the riser pipes. MagiCAD asks the connection height level.

In this example the bottom level of the radiators is 120 mm. Thus, a good value for the upper pipe is e.g. 100 mm.After connection, select pipe options.

Place the return pipe below the supply pipe. Set the pipe distance so that the pipe does not go under the floor.Draw a piece of pipes.



Then connect the pipe to the radiator. If there are many radiators in the same line, connect to the last radiator.

Layer settings for the fall arrow are found under general layers in the project dialog. There is no Part Properties for fall arrow. MagiCAD has only one arrow symbol for now.

NOTE! Arrow changes its place according to viewport`s presentation so the arrow is always located on the side ofthe duct/pipe.


5.14. Set MagiCAD Data to AutoCAD Objects 225

5.14. Set MagiCAD Data to AutoCAD ObjectsGeneralWith this function you can define some MagiCAD data to AutoCAD objects. It makes it possible to include theseobjects in the bill of materials, IFC Export, and MagiCAD Export lists. Defining the dataUsually the AutoCAD object which needs MagiCAD data is a block - for example Air Handling Unit, HeatExchanger...

Start the Set MagiCAD Data to AutoCAD Objects function , and select the object to which you want todefine MagiCAD data. You can change the data afterwards by using the same function.

MagiCAD`s Part Properties function can be used for examine the object. Using the dataAll the data which is defined for the AutoCAD object can be used in Bill of Material list or MagiCAD export list andalso in Dimension text. Data also goes to IFC.

228 5.15. Connection nodes

5.15. Connection nodes You can connect ducts and pipes from active drawing to another drawing with connection nodes. All the technicaldata is transferred vie connection node.The drawing, where the connection is made to, can be in any direction from the active drawing. The drawinglocations in relation to each other are defined in the floor list (Project).

Creating the connection nodeDraw a duct/pipe, right-click the mouse and select the connection node from the popup menu. In this example thestorey height is 3000 mm, so the duct has been drawn to 3000 mm and then connection node is selected.


5.15. Connection nodes 229

ID number – this ID makes all the connection node unique. The same ID numbers must not be used twice withthe connection nodes of the same system type (ventilation, heating, water or sewer system) leading to the samedirection. For example, you cannot use the same ID number with two duct ends leading to the upward. Onlyexception is the risers – then it is recommended to use the same ID numbers in the upper and lower ends of thevertical ducts/pipes. See the Tip.MagiCAD automatically suggest the next free numberDescription – this value can be used in dimension texts and export lists. It is also shown in Connection Nodereport list. Select the direction where the duct/pipe is going. Usually MagiCAD can conclude the right direction forconnection node.None – with this connection node type, you can define the wanted flow and pressure drop. It can be used forexample the situations where there are some existing ductwork in the building, or if the needed air device is notfound from the product database.This - type connection node must have a counterpart with the same ID number in the same drawing (and bothof these connection nodes must be This-type). The flow rate and pressure drop data of the duct is transferred



between the connection nodes. Use this connection node type when you don't want the connecting duct/pipeappear in the drawing. The Flow Data fields are active with None type of connection node In this example the connection node is going upward.

Connecting node to the other drawingIn this example the duct should go from Storey 1 to Storey 2. Storey height is 3000 mm, so the duct was drawn to3000 mm in Storey 1 and then the connection node was added to the end of the duct.



After that the connection node can be taken to the next storey. Open the storey (Storey 2 in this example). Import

the connection node with the Connect Node function .

Select the system group. They can all be selected at the same time.You can import the connection nodes from all systems or from one specific system.Connection nodes will be automatically imported if they are inside of the storey rectangle (Project ->Storeys -> a and b dimensions).If the connection nodes are outside of this area, then activate the Ignore storey dimensions and then you candefine the area from where the connection nodes will be imported. Select the drawing from where the connection nodes will be imported.Add/remove model drawings – if the drawing is not shown in the window, it probably is missing from Modeldrawings list. Add the drawing to model drawings list with this function. When you click OK, connection nodes appear to the drawing and MagiCAD shows the information in AutoCAD’scommand line.



If the connection node is connected, the destination storey is shown inside of brackets ().The height level of the connection node is 0, because the bottom level of Storey 2 is 3000 mm and theconnection node in Storey 1 is in height level 3000 mm.Now you can continue drawing duct/pipe from the connection node. TipsUse always the same connection node ID number at both ends of the vertical duct/pipe. In this case the ductsand pipes can connect to each other when you copy storeys or riser ducts/pipes.



Disconnect NodeSometimes it is necessary to disconnect the connection nodes. It is necessary, for example, if the drawing nameshave been changed – the connection nodes are still connected to the drawings with old name. It would causeerrors in calculations. In these situations, disconnect the connection nodes and then connect them back.

Start the function from Disconnect Node button .

You can select the drawing which connection node connections you want to disconnect. Alternatively you candisconnect them from all drawings.MagiCAD shows the number of disconnected nodes in AutoCAD’s command line.



Connection Node ReportYou can check the connection nodes in active drawing with Connection Node Report function . It is possible to arrange the result to different positions by clicking the heading.

You can zoom the selected connection node to the center of the AutoCAD window


5.16. Partial Insulation 235

5.16. Partial InsulationGeneralIt is possible to define the partial insulation to ducts - without any joint parts. Installing the partial insulationInstall the partial insulation with Change Properties function . Select the function Partial insulation and theinsulation material, then show to points from the duct and the insulation is installed between those points.

Tolerance value is always added to top/bottom level value when using Top/Bottom of buttons. 3D RotateIt is now possible to define an angle to components, when rotating it with 3D rotate function.

--> Angle can be define by writing the angle in degrees to command line or show the angle with mouse. Actuator symbols in duct componentsIt is now possible to select the actuator symbols for duct components (Project --> Ducts --> Parts).



Dimension textsIt is possible to add dimension texts for the AutoCAD objects which has been defined to MagiCAD objects with“Set MagiCAD Data to AutoCAD Objects” function

The orientation of dimension texts is now saved to proxy graphic.

It means that the orientation is now same no matter if the drawing is opened with or without MagiCAD.



SprinklersConnection node type This is now supported in sprinkler pipes. Collision ControlIt is now possible to select an option for avoiding the collision control in cases when there is a provision for void instructure.

Provision for voidsThe presentation of provision for voids is changed so that the length of void is bigger than the wall thickness. Thereal length is of course saved to object data.

Update Drawing Data function update now also the owner information of provision for voids. Bill of material function is now able to count the provision for voids.



Automatic Voids Provision -function will not create the provision for voids if there already is a provision for voidsand the following information remains the same:

• dimensions of existing -and new provision for void is exactly the same• owner information is the same• location is the same

Free TextIt is now possible to create a default text for Free Text. This text can be selected in Free Text -dialog. Define thedefault texts in Project --> Texts for free text



Show Selected Parts OnlyIt is now possible to make the selection also in xref drawings. Options -dialog is opened after the function isstarted.

Scramble connectionIt is now possible to connect the duct to fitting (without reduction) by using the scramble connection function. It isalso possible to start to draw duct from the fitting.



There are also axtra options when the option scRamble connection is active.



IFC ExportOption Select objects added to IFC export -dialog.

It is now possible to use MagICAD Room origin in IFC export.

It is now possible to stretch the IFC Export -dialog. MagiCAD also remember the last used settings. Set MagiCAD Data to AutoCAD ObjectsIt is now possible to add more MagiCAD data to AutoCAD objects:

• Part type - this information is shown in Bill of materials dialog.• Add to BOM - it is now possible to choose if the labelled object is needed in BOM or not



• Convert to MagiCAD object - if this is active, AutoCAD object will be converted to MagiCAD object.Because of this, MagiCAD hide works with labelled objects!

Improvements to some dialogsProperties function was missing from the following dialogs.

• Other Pipe Device• Radiator Selection• Tap Water and Sewer point• Other Pipe Component• Sprinkler Selection• Other Sewer Component• Cleaning Cover

Side MovementMagiCAD have now a new kind of side movement function. Start the function , select the duct and then selectthe side movement by pointing the circle.



Partial InsulationIt is now possible to define the partial insulation to ducts - without any joint parts. Installing the partial insulationInstall the partial insulation with Change Properties -function. Select the function and the insulation material, thenshow to points from the duct and the insulation is installed between those points.



Erasing the partial insulationSelect the duct where the partial insualtion is and after that click the blue circle with cross inside of it.

Duct Drawing OptionsThere is a new "Allow different connection sizes in trunk" option in duct drawing option. With this option MagiCADdoes not create a reduction to T-branches, if the duct size is changed.Instead of reduction, MagiCAD change the size of T-branch connections.



HyperLinkIt is now possible to define the hyperlink to products

SubstationMagiCAD have now support for the substations from manufacturer. There is a new group in Project -dialog(Project -> Pipes -> Parts -> Substation).

Start the installation from Substation Product-button Air Handling UnitsMagiCAD have now support for the AHU´s from manufacturer. AHU´s can be selected to project under the groupFan (Project -> Pipes -> Parts -> FAN).

Start the installation from FAN-button Provision for VoidsIt is now possible to define the dimension for manual provision for voids by showing the object and length indrawing.



Select the dimensions with "<- from Dwg" button. Select the duct/pipe and define the length by showing 2 points.

• sizes - are defined according to Provision for Voids settings• height level - is taken automatically from the object• place of the provision for voids - it is created between 2 points which were shown

Absolute height levelsIt is now possible to select if the height levels are shown as an absolute height levels or from the floor. Thisselection can be done in a dialog's where you can set the height level.

Ducts and fittingsMagiCAD have now support for transfer ducts.



X-branches with different angles are now supported. Other changesPossibility to define Object ID in Set MagiCAD Data to AutoCAD Objects –dialog (manual value). Possibility to select Storey information to Object ID format. MagiCAD Export function did not show the Room information from the AutoCAD objects which has MagiCADinformation (defined with Set MagiCAD Data to AutoCAD Objects –function). New riser -and reduction symbols for pipes (Viewport Preferences).

Change Properties now remember the last used value when changing the duct/pipe series. There are now 15 product variables in devices. Product selection now supports Aligned Integrated Reductions. Production model now supports male-female bends.



It is now possible to draw rectangular bends also with non-standard angles It is now possible to select the "Status from constructor" value (in provision for voids) to MagiCAD Export list. If the real fittings are used, MagiCAD uses the real dimension immediately when drawing the duct (if"Automatically select products (while drawing)" option is active) . New function which turns the bevelled T-branches and outlets to correct direction - even thougt there are many

open ends in network. Start the function from Equalize Branch Directions -button and show the startingpoint of ductwork. Flanges are now also shown with generic rectangular ducts.


Resolved issues 283

Resolved issues Extra length value in duct series changed its place to wrong duct size field in some situations. Sometimes thevalue was also changed to 0. Crossing function did not accept the height difference values, which was possible to use when drawing thecrossing manually. MagiCAD gave the message “Not enough space for all parts”. Target lines were missing if in a section more than one object was selected the to same dimension text.

The size of the Set MagiCAD Data to AutoCAD Objects dialog was changed if the dialog was moved. If the presentation of pipe was 1D, vertical bends were shown with strange graphic in shaded 3D view. Valve which 3D model was shorter than 2D symbol had empty space between valve and pipe connection inshaded 3D view. If the “between” option was used in Find and Replace, MagiCAD crashed. Hide function did not hide the rectangular duct fittings properly, if the duct had an insulation. MagiCAD did not choose the correct pipe size when the pipe was drawn from pump. It was always draw thesame pipe size (smallest). Insert / Edit substation unit did not work if the Use primary connection option was active but main system was notselected. If the LIN file is missing from project files, MagiCAD gave error message in two situations:

• "Version conflict with McHpv_18x64.arx" error appears when using IFC export.• "The drawing is not connected to a project, or the project is invalid" error appears when using Running

index. In some cases, MagiCAD selected a real ductwork fittings even thought the "Automatically select products (whiledrawing)" was not in use. MagiCAD does not give "non-standard branch" message anymore when branches are drawn for example with15, 30, 45 degree bends/branches. Swap setting did not work if the duct size was changed with Part Properties or Change Properties funcion. Unlock duct/pipe size option did not work with Change Properties function. Hide worked wrong if the VP freeze was used in layout. It still hided the object behind other object even thoughtthe object in front was frozen with VP Freeze. There were a small problem in flow summation in Sprinkler Calculation. Now the flows are calculated correctly.


284 Resolved issues

It is not possible to add the absorption material to T-branches anymore. Some fittings (for example X-branches) were rotated to wrong direction. If the BOM was made by using the "Selected drawings" option, also the objects with the status which were notsuppose to take to BOM were calculated to BOM. It was not possible to convert the real integrated reduction product back to generic reduction. When the text format was erased, some of the others text formats was renamed or even disappear from the textformat dialog. MagiCAD did not check correctly the height of the sprinklers design area - Part Properties showed also thesprinklers which were above or below the design area. Colors of pipes in sub systems were shown wrong in IFC. Return -and supply pipes got the same color and hot,cold, circulation pipes got the same color. When sprinkler calculation according to SS-EN 12845 is selected, the option "Ignore short connection branches"is now always active. Side Movement changed the height level of air devices which were connected to the edge of the duct. Other than 90 degree vertical bends did not get the correct symbol (which was defined in viewport settings). MagiCAD used fit-on-length values wrongly. This is now fixed. It is now possible to draw generic, aligned X-branch. Drawings which were added to model drawing list during MagiCAD session were not shown in IFC export list.They were shown after restarting MagiCAD. It is now possible to add dimension texts to angled radiator valve.


MagiCAD Product Modeller 285

MagiCAD Product Modeller It is now possible to model products also to MagiCAD for Revit. For this reason the old shapes have beenremoved from MagiCAD Product Modeller.
