Importing and building compound objects
In FreeCAD, compound objects are objects made with the geometry of several other objects. In other softwares, it is called blocks, symbols or components. It is a very handy way to group geometry under one single object. Any of the objects created with the draft module can be grouped into a compound. The command to create a compound is the Upgrade command. The use is simple, select everything you want to turn into a compound, and press Upgrade. If no other more intelligent shape can be created, they will be turned into a compound.
