I've done some searching on the Cad front and what I'm seeing is mainly archetectural software, if you're a mechanical designer like I am this stuff doesn't cut it and even if you could get the output drawings you wanted, it would really only export to Autocad which I have no use for. Unless I'm designing in solids I might as well get my pencils and vellum out again. So, I'd be forced to use a windows emulator to run a CAD ap, would I really be farther ahead than buying a windows box? How does this work am I essentially running 2 OS's cause I would expect that to hit the efficiency and stability. I'd love to get of the MS toll road if I can.
