How to convert SLDPRT to OBJ

  1. Add your .SLDPRT file - drop it in the box above or click to browse.
  2. Convert it to .OBJ in a few seconds.
  3. Download your new .OBJ file.

What to expect

  • Parametric feature history - sketches, extrudes, fillets, and part relations - does not transfer; the .obj contains only the final triangle mesh.
  • Curved surfaces are tessellated into polygons: a finer tessellation setting produces a closer approximation but a larger file.
  • If the destination is another CAD application rather than a renderer, export to STEP instead - .obj is not suited for CAD-to-CAD interchange.

Frequently asked questions

Can I convert SLDPRT to OBJ without SOLIDWORKS?
Yes. Use our free converter on this page, Autodesk Fusion 360 (free personal tier), or FreeCAD (open-source) - all can read .sldprt and export .obj.
Will the OBJ geometry match the original part?
The shape matches as a mesh approximation. Flat faces are exact; curved surfaces become triangles, and a finer tessellation setting gives a closer result.
Can I convert OBJ back to SLDPRT?
No. Recreating a parametric SOLIDWORKS part from an OBJ mesh is not possible automatically - that requires manual reverse-engineering work.
Will materials and colours be included in the OBJ?
Basic exports carry geometry only. An .mtl material file may accompany the .obj depending on the software and what was configured in the source model.
