This command creates a compound of any kind of topological shapes. These can be solids or meshes or any other kind of topological shapes.

A compound is a set of shapes grouped into one object.


Mark the topological shapes to be added to the compound in the tree view and choose Part → Compound → Make Compound


A compound containing pieces that intersect or touch is invalid for Boolean operations. Because of performance issues, checking if the pieces intersect is not done by default. Automatic geometry check (available for Boolean operations) is disabled for part compound as well.

To turn this check on go to Tools → Edit Parameters → Preferences... → Mod → Part → CheckGeometry → RunBOPCheck and set the parameter to true.
