Well I also have a full time job where large CNC machinery is used. I'm not sure how specific the workflow is to various machines and how much is a standard process. I do 3D CAD with no problem as that is the day job, it's really a case of how I take that data and get it into a program that controls the machine.

I know the proxxon software allows you to import a DXF, that is something I can generate with no problems.
