How to convert BREP to DXF
- 1Add your BREP fileDrop the .brep file into the box, or pick it from disk. Multiple files are converted one after another.
- 2Pick DXF as the outputDXF is already selected on this page. Adjust scale, up axis or triangle budget if the target application is picky.
- 3Download the resultThe .dxf file is written locally and appears as a download button next to your file.
About BREP
BREP is the on disk form of an Open CASCADE shape: exact topology and geometry with no application metadata. FreeCAD and CAD tools built on OCCT use it as a lossless internal exchange format.

- Open CASCADE
- CadQuery
- Salome
About DXF
DXF is the published counterpart to AutoCAD's DWG. It is mostly used for 2D drawings, but the 3DFACE entity carries triangulated surfaces, so meshes can be handed to CAD and CAM tools that never learned to read mesh formats.
- DXF is supported as an output only. Meshes are written as 3DFACE entities, one per triangle.
- AutoCAD
- BricsCAD
- LibreCAD
- Fusion 360
- Rhino
Questions
Is this BREP to DXF converter free?
Yes. There is no account, no daily quota and no watermark. The tool is a static web page and the work is done by your own CPU, so there are no server costs to pass on.
Are my files uploaded anywhere?
No. MeshFormat loads a WebAssembly build of the geometry kernels into your browser and reads the file locally. You can open the network tab and confirm that nothing leaves the page, or disconnect after the page has loaded and keep converting.
How large can a BREP file be?
The practical limit is your available memory rather than an arbitrary cap. Models up to a few hundred megabytes work on a normal laptop; very dense scans convert faster if you lower the triangle budget in the options.
Anything to know about DXF output?
DXF is supported as an output only. Meshes are written as 3DFACE entities, one per triangle.
Which programs open DXF files?
AutoCAD, BricsCAD, LibreCAD, Fusion 360 and most other tools that work with CAD data read .dxf directly.
