3D Max - Insert shapes instead of rim.

Sims_doc

So, Lets just say i've got a cube and i insert it normally it would follow the rim of the object but lets say i want to insert another shape say like a rectangle or circle how would one do that without resorting to manual methods.

ProBoolean. Plus a little manual cleanup, to kill concave polygons, and the occasional duplicate vertex.

The Geopoly button in the Ribbon will create shapes based on the number of edges available. For example, a face with 6 edges will become a hexagon, 8 > octagon, and so forth.

Not exactly what you are asking for, but it's similar.
