How to convert STP to DXF

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

What to expect

  • 3D data does not transfer - DXF captures only the 2D geometry you select (a projection, face outline, or cross-section); the solid body, material, and feature history are lost.
  • Circular edges may export as true arcs or as polyline segments depending on exporter settings; prefer arc export in FreeCAD's DXF options for accurate laser-cutting paths.
  • If your .stp is a multi-part assembly, isolate the individual part or face first - exporting an entire assembly to a single DXF rarely gives useful results.

Frequently asked questions

Will dimensions be accurate in the exported DXF?
Yes, if the original STP geometry is correct and you export at 1:1 scale. Always check units after import - STP files can be in millimetres or inches.
Can I convert STP to DXF for free?
Yes - our converter above is free, FreeCAD is free and open-source, and Autodesk Fusion 360 is free for personal and hobby use.
Why does my exported DXF have missing lines or look wrong?
The view projection may have missed edges, or the DXF version is mismatched - try DXF R14 or R2000 format in FreeCAD's export options and verify that scale and units match.
Can I recover the 3D model from the DXF?
No - a DXF is a snapshot of 2D contours and cannot be used to reconstruct the original 3D solid. Keep your original .stp file for any further 3D work.
