Supported File Types

The following file types are supported in Paperless Parts for viewing and quoting:

  • STEP (.step, .stp)
  • SolidWorks (.sldprt)
  • Mesh (.stl, .3mf)
  • IGES (.iges, .igs)
  • Print (.pdf, image files)
  • Unigraphics/NX (.prt)
  • Inventor Part (.ipt)
  • Parasolid (.x_t, .x_b)
  • ACIS (.sat)
  • Catia (.catpart, .3dxml)
  • Solid Edge (.par)
  • Rhino (.3dm)
  • Vector (.dxf, .dwg)

You can upload other file formats but they will not be viewable in the system.

Use a format we don't support? Contact and let us know.

For Best Results, Use STEP and Native CAD File Formats

When quoting, upload STEP files or native CAD file formats like SLDPRT from SolidWorks to maximize the geometric analysis done to power your quotes.

Uploading SolidWorks Assemblies

You can upload SolidWorks Assemblies by uploading a zip file generated by the Pack and Go feature in SolidWorks. Learn more about Pack and Go.

Limitations with Mesh and Surface CAD Formats

CAD file formats like STLs and IGES are not analyzed as deeply by the Paperless Parts platform because they only contain mesh and surface information that cannot be interpreted for our manufacturing analysis. Ask your customer for a STEP file instead.

Note: Converting an STL or IGES to a native or neutral CAD format will not work either. The STEP must be exported from the native CAD format.
