A comprehensive list import and export file formats supported by Onshape.

Onshape automatically imports and translates these CAD file formats for parts and assemblies, including wire bodies and sketch curves.

For more on importing parts and assembly files see, Importing MCAD files.

For all assembly files, you must place all parts and the assembly in a zip file and import the zip file into an Onshape document. The zip file name must match the name of the top-level assembly. For more information, see Importing Files.

Non-CAD files

Onshape supports a number of common and native CAD file formats for both import and export. You are also able to import other, non-CAD files into Onshape for reference (for example, viewing or storage only).

Non-CAD files that are able to be imported into Onshape include:

  • .pdf
  • .mp4
  • .png
  • .jpg/jpeg
  • .svg
  • .gif
  • .txt
  • .md

Files that are able to be uploaded but not viewed include:

  • Any programming language files (py, json, java, js)
  • .mov (this may depend on browsers and allowed plugins)
  • .csv
  • .doc/docx

Onshape exports parts, Part Studios, Assemblies, Drawings, and tabs containing other imported CAD files to these CAD formats.
