Uncool dude - I have a great need to start. I have a machine that is a prototype and has removed two union workers off a 10 month install...saved a ton of cash. I want to begin a division to manufacture these machines, and sell them. So I am (at home) using AutoCAD 2000i to start the long process off drawing individual parts and then want to go 3d for assembly drawings, especially for presentations to get approval and financing.
