Overview: In this lesson, you will learn how to apply compositions to 3D solids.
After completing this lesson, you will be able to:
- Use the BIM Compositions panel to attach a composition to a solid
- Use the Compositions editor to create, delete, or edit compositions in a project
- Utilize the physical materials library to create single-ply compositions
- Display composition plies
- Remove a composition from a solid

Compositions can be assigned to the various solids of a BIM model. They can be either multiple or single-ply. In BricsCAD, predefined compositions of each building element type are stored in the library database. They can be found in the BIM Compositions panel and Compositions Editor.
- BLCOMPOSITIONS () to open the compositions dialog box.
- BLMATERIALS () to open the materials dialog box.
Or use the BIM Compositions dockable panel.
|(2) Composition types list|
|(3) Search field||Filters the list of the compositions as you type. Only compositions that contain the current search term are displayed.|
|(4) Available compositions||All compositions of the selected type in both the Library and the Project database display, unless the 'Show only compositions in project ...' menu option is selected.|
BIM Composition Editor
The BIM Composition editor is a dialog box that contains options to create, modify, and delete a composition. Using the composition editor you can also sort the compositions by category and view the properties of the composition.
The BLCompositions command opens the BIM Compositions Editor:
|(5) Composition category selection||Filters by category: Wall, Slab, Roof or Generic.|
|(6) New composition||Creates a new composition.|
|(7) In project||
Displays the compositions of the selected category (wall, slab…) in the Project database.
|(8) In library||
Displays the compositions of the selected category (wall, slab…) in the Library database.
|(9) Preview pane||Displays the currently selected composition.|
|(10) Name field||
Displays the selected composition name. You can change the default name.
|(11) Category drop-down box||Displays a category for the new composition.|
|(12) Structure grid||
Displays the material and thickness of the various composition plies. The ply on top will become the outer face of the solid.
|(13) Add ply button||Opens the physical materials display box which allows you to choose a material from the library or project database. Here you can also create a new material.|
|(14) Properties grid||Shows the properties of the selected composition.|
|(15) Custom properties||Opens the custom properties dialog.|
Whether the various plies of a composition shown in the 3D model is controlled through the LevelOfDetail user preference.
To set the Level of Detail in a model, do one of the following:
- Type LEVELOFDETAIL in the command line, then type 0 (=OFF) or 2 (=ON).
- Click the Level of Detail icon in the Home/View panel in the ribbon or the BIM toolbar.
The icon has two states:
- Unpressed (= OFF):
- Pressed (= ON):
Procedure: Create a new composition
Use either the Project or the Library database to create BIM compositions.
Step 1: Add a composition
- Open the BIM composition editor. Do one of the following:
- Select the Open the compositions dialog ... in the menu on the Compositions panel.
- Type BLCompositions in the command line.
Click the New icon on the left-hand side of the compositions toolbar. A new (empty) composition is added to the selected database.
Step 2: Edit the composition
Select the new composition from the database.
Type a new name in the Name field.
Use the Type drop-down box to specify the composition type.
Click the Add Ply button on the right-hand side of the compositions editor to include a ply.
The Physical Materials dialog displays:
Select a material either in the Project or the Library database, then double-click or press the OK button to include this material in the composition.
Optional Right-click the material and choose Make composition (16) from the context menu to create a single-ply composition.
Click the Thickness field (17) to modify the thickness of a ply in the Structure grid.
Enter a value in the field (18) and press Enter to accept it. The overall thickness of the composition is updated accordingly.
Repeat the previous steps to add more plies.
To change the order of the plies, drag the ply number (21) to the desired position.
The overall thickness of a composition equals the sum of the thicknesses of the composing plies.
The thickness of a ply can be either locked or unlocked.
- Locked thickness (19): The thickness of the ply is fixed.
- Unlocked thickness (20): The thickness of the ply is variable.
Note: Only one ply in a composition can have an unlocked thickness. As a result, the total thickness of a composition can be:
- Fixed: all its plies have locked thicknesses.
- Minimal: the composition contains at least two plies and one ply has an unlocked thickness. The minimum thickness equals the sum of the thicknesses of the locked plies.
- Free: a single ply composition with an unlocked thickness.
The thickness of a ply can be unlocked only if the Allow Custom Thickness property of the material is Yes.
Note: When the thickness of a ply in a composition is modified, the solids which include this composition will not be updated automatically. To re-apply the overall thickness of a composition to the solid use the BimUpdateThickness command.
Editing a composition
Select the composition in either the In Project or the In Library list on the Compositions dialog.
The current settings of the selected composition are displayed.
Type a name in the Name field.
Click the Category button, then select a composition category: Wall, Slab, Roof or Generic.
Composition categories are used to filter the list of the compositions and the Compositions dialog.
Edit the composition plies in the Ply grid.
Here you can:
- Modify the thickness of a ply
- Change the material of a ply
- Add a ply
- Modify the order of the plies
- Delete a ply
Edit the properties of the composition in the Properties grid.
Edit the Tags field: tags are separated by commas. Tags are case sensitive.
Click the Browse button () to open the Tags dialog.
Click the New Item button () to add a new tag at the bottom of the list.
Select a tag in the list then click a tool button:
- : edit the selected tag
- : delete the tag
- : move the tag up
- : move the tag down
Edit the Comments field.
Click the OK button to save the changes.
Modify the thickness of a ply
The thickness of a ply can be modified only if the Allow Custom Thickness property of the Material is Yes.
Click the Thickness field in the Ply grid of the composition.
Type a value and press Enter. The overall thickness of the composition is updated accordingly.
Note: When the thickness of one or more plies in a composition has been modified, the solids which have this composition applied are not updated automatically. Use the BimUpdateThickness command to reapply the overall thickness of a composition to the solid.
Change the material of a ply
Double click either the Pattern or the Name field of the ply. The Materials dialog displays.
On the Materials dialog double click a material in either the In Project or the In Library list. The selected material is applied to the ply.
Optional Edit the thickness of the ply.
Add a ply
A new ply will be added above the selected ply. You can drag the ply to a different position afterward.
Select a ply in the composition.
Click the Add Ply tool button. The Materials dialog is displayed.
On the Materials dialog double click a material in either the In Project or the In Library list. The selected material is applied to the new ply.
Optional Edit the thickness of the ply.
Optional Drag the ply to a different position.
Modify the order of the plies
The plies of a composition are ordered, top to bottom, from outside to inside.
Drag the ply number (first column in the ply grid) to the desired position.
Delete a ply
Select the ply in the composition.
Click the Delete tool button.
The following procedure can be used in both the BIM Compositions panel and the Compositions editor.
Select the compositions(s) in the source database. Press and hold the Ctrl key to select multiple compositions.
Do one of the following:
Drag the selection to the other database.
Right-click and choose Copy to Library in the context menu.
If the value of the CopyOverwrite user preference is 0 (zero) a dialog box displays if the composition already exists in the target library.
Optional Check the Apply to all compositions in this operation option.
Select the compositions in the In Project or In Library list on the BIM Compositions panel or the Compositions editor.
Do one of the following:
Right-click and choose Delete in the context menu.
Click the Delete button (Compositions editor only).
Note: Compositions that are used in the project cannot be deleted from the project database.
