Once again, Thorsten Lemke makes me feel stupid. :-) CADintosh has a lot of tools, and like GraphicConverter, I can tell that there's a lot of power there. Unfortunately, my drawings in GC and my CAD in CADintosh look like a toddler's sketches. Maybe I'm too addicted to the idea of 3D CAD to be happy with 2D CAD? Anyway, I can hardly draw a straight line with this software, and I'm afraid I can't recommend it.
BTW: The crash problem referred to below has apparently been fixed...
