Import / Export / Convert common 3D file formats



Import, export and convert many of 3D file formats including STL (stereolithography), SKP (Trimble SketchUp), OBJ (Wavefront), 3DS (3D Studio), SAT (Standard ACIS Text) and more.

Autoconverter allows to import, export and convert between the most common 3D file formats as a native Windows executable. It supports many of 3D file extensions including STL (Stereolithography), OFF (Object File Format), OBJ (Alias Wavefront Object), 3DS (3D-Studio File Format), IV (Inventor File), SAT (Standard ACIS Text), PLY (Stanford Polygon Format), VRML (Virtual Reality), 3DM (Rhinoceros 3D Model), SKP (Trimble SketchUp), DAE (Collada), STEP (STandardized Exchange of Product), IGES (Initial Graphics Exchange Specification), BREP (Boundary Representation) and DXF (Drawing Exchange Format).





  • Import STEP, IGES, BREP, 3DS, OFF, STL, OBJ, PLY, 3DM, DAE and SKP file formats.
  • Export STEP, IGES, BREP, STL, OFF, OBJ, 3DS, IV, PLY, VRML, 3DM, DXF, DAE, SKP and SAT files.
  • Convert triangulated polyhedral meshes into faceted BREP shapes (manifold solids).
  • Unify normals, invert facets, merge and split shells mesh editing commands.
  • Automatically fill up mesh holes to fix & heal 3D model geometry.
  • Calculate mass, centroid, moments of inertia, radius of gyration and principal moments.


  • Microsoft Windows operating system with minimum 2GB RAM.
  • 64 bits platform for large files with million of faces recommended.

Evaluation Version
