Automatic Cutouts in Floors and Ceilings
You can define your structural, electrical or plumbing families with openings. When you place the families
into a building component in your project, they will automatically create an opening in that component.
For example, you could create a light fixture and define it with an opening. When you place the component,
the opening in the ceiling or floor is created automatically.
Purging Unused Families
The Purge Unused command unloads unused families and family types from a project, reducing the file size
of the project. If the project is workset-enabled, all worksets must be open to use this command.
1 Click File menu
➤
Purge Unused.
The Purge unused dialog opens and lists all the families and family types that you can unload
from the project. The layout is similar to the Project Browser with a tree structure that you can
navigate by clicking the + and - symbols.
2 Select the desired families to unload from the tree structure. To select all families, click Check
All. To clear the selection of all families, click Check None.
3 Click OK to continue the purge, or click Cancel to cancel it.
TIP After you have issued the command, at least one type of each system family remains, even if it is not used.
System families are any families not created from a family template file.
