There are several "CAD lite" systems available if you don't actually need dimensional accuracy though. There's a model boom in DnD circles around sharing 3D models, slicing them up, gluing them together, and making your own designs by basically digital kitbashing. My friend is filling up hard drives with 3D models DMs share.
