Convert BREP to OFF Online
Convert BREP to OFF in seconds. BREP is a raw boundary-representation CAD export; OFF's strength is this: a plain, easy-to-parse mesh structure. No software installation required: you upload the file here and the conversion runs on our servers.

Why Convert BREP to OFF?
This conversion comes up whenever you need geometry-processing research and academic mesh exchange instead of exchanging exact CAD surface geometry between engineering tools. BREP and OFF serve genuinely different purposes, so moving between them isn't just a formality.
If you need a file built for geometry-processing research and academic mesh exchange but only have one built for exchanging exact CAD surface geometry between engineering tools, converting is usually the fastest path — BREP and OFF serve different enough purposes that recreating the asset from scratch rarely makes sense.
BREP is a raw boundary-representation CAD export, commonly used for exchanging exact CAD surface geometry between engineering tools. That focus comes with a real limitation: a lower-level format most non-CAD software has no importer for. OFF doesn't share that problem — its strength: a plain, easy-to-parse mesh structure.
How to Convert BREP to OFF
- Upload your BREP file.
- MiConvert converts it to OFF, aiming to preserve what makes OFF useful: a plain, easy-to-parse mesh structure.
- Download the converted OFF file.
- Use it directly with geometry-processing research tools.
Key Conversion Features
- Understands that BREP is a raw boundary-representation CAD export and OFF is a simple research-origin polygon mesh format, rather than treating the conversion as a blind format swap
- Converts BREP into OFF, aiming to preserve what matters most: a plain, easy-to-parse mesh structure
- Built to handle the real-world quirks of files meant for exchanging exact CAD surface geometry between engineering tools, not just a textbook version of the format
- Produces output ready for geometry-processing research tools, picking up right where CAD kernels like OpenCascade left off
- Keeps the parts of your file that matter for geometry-processing research and academic mesh exchange intact, even though the source was built for exchanging exact CAD surface geometry between engineering tools

Frequently Asked Questions
Do I need CAD kernels like OpenCascade installed to convert my file?
No — the conversion happens entirely on our servers. You don't need CAD kernels like OpenCascade, and you don't need geometry-processing research tools either unless you plan to open or edit the OFF result afterward.
How long does the conversion take?
Most conversions finish in 10-30 seconds. Larger or more complex files can take up to a minute.
Can I convert the file back from OFF to BREP afterward?
Only what OFF actually carries can come back — anything specific to BREP's role in exchanging exact CAD surface geometry between engineering tools that didn't survive the original conversion won't reappear.
Will I lose anything converting BREP to OFF?
Converting to OFF means adapting to a real constraint: minimal — no materials, textures, or color support. Anything BREP carries — built as it is for exchanging exact CAD surface geometry between engineering tools — that has no equivalent there won't make the trip, but the core content converts faithfully.
What happens to features specific to BREP that OFF doesn't have?
BREP's real strength — stores exact mathematical surfaces rather than an approximated mesh — has no equivalent once converted, since OFF's constraint is: minimal — no materials, textures, or color support.
