Why Convert BREP to USDZ?
BREP works well for exchanging exact CAD surface geometry between engineering tools, but has a real limitation: a lower-level format most non-CAD software has no importer for. Converting trades that for this: a single file ready for iOS AR viewing with no external references.
The short version: BREP is optimized for exchanging exact CAD surface geometry between engineering tools, USDZ is optimized for Apple's AR Quick Look distribution format, and this converter exists for the moment those two needs don't line up.
If you need a file built for Apple's AR Quick Look distribution format but only have one built for exchanging exact CAD surface geometry between engineering tools, converting is usually the fastest path — BREP and USDZ serve different enough purposes that recreating the asset from scratch rarely makes sense.
How to Convert BREP to USDZ
- Upload your BREP file.
- MiConvert converts it to USDZ, aiming to preserve what makes USDZ useful: a single file ready for iOS AR viewing with no external references.
- Download the converted USDZ file.
- Use it directly with iOS AR Quick Look.
Key Conversion Features
- Free for files up to 50MB, 100MB for registered accounts
- Keeps the parts of your file that matter for Apple's AR Quick Look distribution format intact, even though the source was built for exchanging exact CAD surface geometry between engineering tools
- Understands that BREP is a raw boundary-representation CAD export and USDZ is a zipped, self-contained package of USD, rather than treating the conversion as a blind format swap
- Purpose-built for the shift from exchanging exact CAD surface geometry between engineering tools to Apple's AR Quick Look distribution format, not a generic pass-through
- No local software installation required for either side — not CAD kernels like OpenCascade, not iOS AR Quick Look — everything runs in the cloud

Frequently Asked Questions
What software works with the converted USDZ file?
USDZ is used by iOS AR Quick Look. If you were working with CAD kernels like OpenCascade (which produces BREP), this conversion is the direct bridge between the two.
Is there a file size limit for this conversion?
Free conversions handle files up to 50MB; registered accounts get up to 100MB.
Can I convert the file back from USDZ to BREP afterward?
Only what USDZ 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.
Is this conversion free?
Yes — free for files up to 50MB, with a 100MB limit for registered accounts, no subscription required.
How long does the conversion take?
Most conversions finish in 10-30 seconds. Larger or more complex files can take up to a minute.
