I would like to find a 3d cad program similar to Pytha so I can get back into drawing. But since pytha doesn't have a mac version and the pc version is 7,000 I figured I'd look for an alternative. I've tried sketchup, pretty amateurish to say the least. It's more a program where you draw lots of lines that look 3d as opposed to rendering real 3d shapes. Kinda like having to go back to windows 3 after you've been on windows 7... However I haven't tried pro so who knows. Anyone got any suggestions.
