My buddy's Mill is a Fadal. I looked up a list of their G codes and most of them are the same. What I didn't see where the G70, G71, and G72 codes, which are all the bolt hole circle, arc, and array codes. The project I am making has 10 bolt hole circles, with 6 holes per circle.

I downloaded Autocad and have managed to make a drawing for the part I want to make. I also downloaded Mastercam but haven't used it yet.
