Import / Export / Convert 3D file formats with Nurbs shapes



Import, export and convert 3D file formats with Nurbs solid shapes including STEP (STandardized Exchange of Product), 3DM (Rhino), IGES, BREP and more with automatic surface reconstruction from triangle mesh files.

Autoshaper allows to import, export and convert between 3D solid modelling file formats with smooth Nurbs shapes as a native Windows software. It supports many of 3D file extensions including 3DM (Rhinoceros 3D Model), STEP (STandardized Exchange of Product), IGES (Initial Graphics Exchange Specification), BREP (Boundary Representation) and IFC (The Industry Foundation Classes). It allows also to import and reconstruct nurbs surface from triangle mesh file formats including SKP (Trimble SketchUP), OBJ (Alias Wevefront), OFF, STL, 3DS, PLY, DAE, VRML and point clouds data from ASC or XYZ files.





  • Automatic surface reconstruction from ASC, XYZ point cloud files.
  • Surface reconstruction from STL, OBJ, SKP, OFF, 3DS, PLY, DAE and VRML mesh files.
  • Import STEP, IGES, BREP, 3DM and IFC file formats with Nurbs shapes.
  • Export STEP, IGES, BREP and 3DM solid modeling files.
  • Support for metric & imperial units in STEP and IGES solid files.
  • Editable color, transparency & name for single shape components.
  • 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 thousands of shapes recommended.
