This is yet another topic I don't know much about.
Is it possible to "rent" time on a company's CNC machine somewhere? I have an idea for something to sell at renfaires, and the best way to make it happen would be using a CNC machine to create the parts.
I have little if no clue how CNC stuff works, other than you stuff a DXF file and a metal billet in one end, and out comes the finished part, perhaps anodized if the machine has that capability, and you are doing aluminum.
Also, how hard is it to get used to doing 3D stuff with AutoCAD? I've not used a CAD program since I was doing stuff with CATIA and AIX ages ago.
