Supported File Formats

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.

Part files

• Parasolid B-rep (.x_t or .x_b) from v10 to v33.0.229

  Parasolid is the Onshape preferred import format.

• Parasolid mesh (.xmt_txt or .xmt_bin) from v28 to v29 (view and reference meshes only, unable to edit a mesh)
• ACIS (.sat) up to R21, 2018 1.0
• STEP (.stp or .step) AP203, AP214, and AP242 (geometry only)
• IGES (.igs or .iges) up to 5.3
• CATIA v4 from 4.15 to 4.24 (via an Assembly .zip file)
• CATIA v5 from R7 to R30 (v5-6R2020)
• CATIA v6 R2010x to R2013x, R2015x, R2016X, R2020X
• SOLIDWORKS (.sldprt) 1999 to 2021
• Inventor 9 up to 2021
• Pro/ENGINEER, Creo from Pro/E 2000i to Creo Parametric 6.0
• Creo 7.0
• JT (.jt) up to 10
• Rhino (.3dm) up to 7
• STL (.stl) (view and reference meshes only, unable to edit a mesh)
• OBJ (.obj) (view and reference meshes only; unable to edit a mesh)
• NX UG15.0 through NX12.0.2.9

  NX1847, latest version NX 1847.2400, and NX1851

• Solid Edge (.par and .psm) 10 through 2021

  Importing Solid Edge sheet metal files (.psm) will not result in sheet metal models in Onshape. You have the ability to reference imported faces in the Sheet metal model and use the Thicken option to create an Onshape sheet metal model.

• NX1847, latest version NX 1847.2400, and NX1851

• Solid Edge 10 through 2021 (via a .zip file)

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.

Drawing files

• AutoCAD (.dwg) up to 2018
• DXF (.dxf) up to 2013, 2018
• DWT (.dwt) 2013, 2018

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.

For more on exporting see, Exporting Files.
