STP → DXF

Convert STP to DXF

Turn an STP CAD model into a DXF mesh. Curved surfaces are meshed finely enough to stay smooth, and the part keeps its real size and orientation.

How to convert STP to DXF

  1. Add your STP file

    Drop it on the converter above or click browse. It opens in your browser, so nothing is uploaded.

  2. Check the format is DXF

    DXF is already selected. You can switch to any other output from the menu.

  3. Convert and download

    Click Convert and your DXF file is ready in seconds. Download it straight away.

What is STP?

STEP stores exact CAD geometry: true planes, cylinders, cones and freeform surfaces joined into solids. It is the standard way to move parts between CAD systems such as SolidWorks, Fusion 360, Inventor, CATIA and FreeCAD.

Full name
ISO 10303 (Standard for the Exchange of Product Data)
Type
Exact CAD geometry
Used in
SolidWorks, Fusion 360, Inventor, CATIA, FreeCAD, Onshape
Strength
Exact, editable geometry that every CAD program can open.
Limits
Not used directly by slicers or game engines; it has to be meshed first.

What is DXF?

DXF is AutoCAD's exchange format. We write your model as 3D faces that AutoCAD, LibreCAD and most CAD programs can open.

Full name
AutoCAD Drawing Exchange Format
Type
Triangle mesh
Used in
AutoCAD, LibreCAD, DraftSight, laser and CNC software
Strength
Opens in AutoCAD-compatible software.
Limits
3D faces only; not a solid model.

Good to know

STP stores exact surfaces; DXF needs triangles. We mesh each surface with a deviation of 0.05% of the part's size, which keeps holes and fillets smooth for printing and rendering.

Dimensions stay in the units of the original file, usually millimetres.

Questions

Will curves look faceted?

No. Curved faces are meshed with a tight tolerance, so holes and fillets stay smooth.

Does it keep the size of my part?

Yes. The mesh has the same dimensions as the CAD model.

Are my files uploaded?

No. Everything runs in your browser.
