Yeah this is way out there, I do use Cartomap Cad for iPad and like it very much. Cartomap is the best Cad App for th eiPad hands down. Where I work ha just bought a CNC Router with a Fanuc control. Routers run off G Code that is generated from a Cam software package. I did some drawings in Cartomap on my iPad and sent them to the Cam software and it put out the G Code I then loaded it to the Router and ran it. Worked fine. Maybe an App to make G Code? Yeah not much call for that but it would be cool to design something on your iPad from scratch and send it straight to a CNC router to be cut! To far out there?
