Is there a way (in python) to add a sub-face to a face? I want to represent conceptually the idea of a window or a wall as a sub-face to a wall face. However, I need the entity to stay as a "Part.Face" rather than a compound as I need to build a shell/solid out of it. I tried adding the outer wires and that kind of worked, but I was getting a solid face with a hole in it. Is there a way to make a "Face" the Subshape of another "Face". Any help is greatly appreciated.
