ArtiFix supports over 50 file extensions. You can convert between STL, OBJ, PLY, GLB, GLTF, FBX, 3MF, DAE, WRL, OFF, DXF and export to 3D PDF. It also supports DXF (2D CAD), IFC (BIM), geospatial formats (SHP, GeoJSON, KML, GPX), SVG and documents.
ArtiFix cannot directly open proprietary formats (DWG, SKP, RVT) because they require commercial libraries. However, simply export the file to DAE (Collada) or OBJ from the original software (AutoCAD, SketchUp, Revit) to access all ArtiFix services, including conversion to STL, 3D PDF and other formats.
