My grandson wants to do mechanical design on his IMac. Since he's an Apple man he doesn't want to switch to PC to get capability. Are there any inexpensive Cad/Cam (mechanical design) software programs for Apple?
Inexpensive software usually meets limited demands.A quick search in the Apple site, either at "downloads" or "made4mac" could give results.Versiontracker, Macupdate etc can also give solutions.
Another software which has educational pricing is Form-Z which is a 3-D/2-D modeling and drafting software. None of these first few programs are that easy to use, but with some diligents and reading through tutorials or guide books almost anyone can do it.
