ArtCAM was famous for its "Relief" modeling. If your primary work involves organic shapes (like rings, pendants, or sculptural pieces), is the superior modeler. However, Rhino is purely CAD; it does not generate toolpaths (G-code) by itself. You must pair it with a CAM plugin.
Carveco is essentially ArtCAM under a new name, maintaining the same design philosophy and workflows while modernising it for current systems. autodesk artcam alternative
