Re: [CAD_CAM_EDM_DRO] Re: Could it be this easy? (Yes.)

Whilst we are on the subject can anyone tell me if/how i can turn 3D Studio
Max nurbs based objects into g code?.

I have tried converting them to dfx files which is fine but its always 2d
and i wanted to try some 3d stuff.

Cost as always rears its ugly head and since i have 3D Studio and am already
fairly familier with using it I would really only require a converter or
something?.

Nick
