Overview ArtCAM (originally from Autodesk, later acquired by Autodesk and now discontinued as a standalone product) was a leading software for creating 3D relief models for CNC machining, particularly for woodworking, engraving, and mold making. While the software itself is no longer officially sold, a massive ecosystem of relief files (in .art, .3d, .stl, .v3m, etc.) still circulates online. “Free ArtCAM relief files” are user-shared or sample 3D models intended to be machined with CNC routers, laser engravers, or 3D printers.
