The discontinuation of ArtCAM felt like a death sentence for many CNC operators, but the acts as a resurrection tool. Whether you use Carveco (the successor), ArtCAM Explorer (the free way out), or outsource the task, converting your .art files to open standards like STL and DXF is not optional—it is essential.
Relief files are strictly 3D height maps. While proprietary, they are easier to translate than .art files.
If you have ArtCAM installed, you can convert your 3D relief into a triangular mesh and save it as an STL for 3D printing or use in other CAD software.
