I am working on a very complex building where each floor is a different
shape and the floors get smaller as the building gets taller. This leads to
the need for many partial roofs. Is there an easy way to do this? The
geometry is rather complex and if there is a way to accomplish this in the
wizard I would love to know.

Also, does anyone know what the implication would be if I just put a roof
over the entire floor even though technically this is not the case?

Thanks in advance!
