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 filesCopy link

• Parasolid B-rep (.x_t or .x_b) from v10.0 to v34.1

Parasolid is the Onshape preferred import format.

• Parasolid mesh (a zip file containing an x_t and an xmm_txt, or a zip containing an x_b and an xmm_bin, or an x_b file) from v28.0 to v34.1 (view and reference meshes only, unable to edit a mesh)
• Parasolid mixed model, representing mesh and B-rep, in the form of a zip file containing an x_t and an xmm_txt, or a zip containing an x_b and an xmm_bin, or an x_b file from v32.0
• ACIS (.sat) up to 2021 1.0
• STEP (.stp or .step) AP203, AP214, and AP242 (geometry and face color 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 (v5-6R2022, R32)
• CATIA v6 R2010x to R2013x, R2015x, R2016X, R2020X
• SOLIDWORKS (.sldprt) 1999 to 2022
• Inventor 9 up to 2022
• Pro/ENGINEER, Creo from Pro/E 2000i to Creo Parametric 8.0
• JT (.jt) up to 10.7
• 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, NX UG 1911, NX 1915, NX 1919, NX 1926 through 1946, NX 1965, NX 1969, NX 1973, NX 1847, latest version NX 1847.2400, NX 1851, NX 1980, NX 1984, NX 1988, NX 1992, NX 1996, NX 2000, NX 2007 Series, 2008, 2011, and 2015
• Solid Edge (.par and .psm) 10 through 2022

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.

Non-CAD filesCopy link

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.
