The luthier I am apprenticing under uses Rhino 3D modeling software for PC for templates, then uses those files for the CNC machine. I, however, use a Mac with OSX. Is there a 3D program for Mac that is directly compatable with Rhino? Does such cross-platforming exist?
Any CAD software that saves lines and splines as .dxf files is fine. Most, if not all, do have this export feature on any platform ( Mac, PC, Linux, Onyx )
