Convert BREP to PLY Online
Convert BREP to PLY in seconds. BREP is a raw boundary-representation CAD export; PLY's strength is this: can store per-vertex color and custom properties directly on the mesh. No software installation required — everything runs in your browser.

Why Convert BREP to PLY?
The short version: BREP is optimized for exchanging exact CAD surface geometry between engineering tools, PLY is optimized for 3D scanning output, carrying per-vertex color alongside geometry, and this converter exists for the moment those two needs don't line up.
Our engine reads a file built around exchanging exact CAD surface geometry between engineering tools and rebuilds it aiming to preserve this: can store per-vertex color and custom properties directly on the mesh — rather than producing a generic, lowest-common-denominator result.
PLY is the Stanford Triangle Format, built around 3D scanning output, carrying per-vertex color alongside geometry. Converting from BREP — built around exchanging exact CAD surface geometry between engineering tools instead — closes that gap.
How to Convert BREP to PLY
- Upload your BREP file.
- MiConvert converts it to PLY, aiming to preserve what makes PLY useful: can store per-vertex color and custom properties directly on the mesh.
- Download the converted PLY file.
- Use it directly with 3D scanners and scan-processing software.
Key Conversion Features
- Purpose-built for the shift from exchanging exact CAD surface geometry between engineering tools to 3D scanning output, carrying per-vertex color alongside geometry, not a generic pass-through
- No local software installation required for either side — not CAD kernels like OpenCascade, not 3D scanners and scan-processing software — everything runs in the cloud
- Understands that BREP is a raw boundary-representation CAD export and PLY is the Stanford Triangle Format, rather than treating the conversion as a blind format swap
- Produces output ready for 3D scanners and scan-processing software, picking up right where CAD kernels like OpenCascade left off
- Bridges the gap between BREP's focus on exchanging exact CAD surface geometry between engineering tools and PLY's focus on 3D scanning output, carrying per-vertex color alongside geometry

Frequently Asked Questions
Is there a file size limit for this conversion?
Free conversions handle files up to 50MB; registered accounts get up to 100MB.
What's the real difference between BREP and PLY?
BREP is built around exchanging exact CAD surface geometry between engineering tools (a raw boundary-representation CAD export). PLY is built around 3D scanning output, carrying per-vertex color alongside geometry instead (the Stanford Triangle Format) — different enough that this is a genuine format conversion, not just a rename.
Is this conversion free?
Yes — free for files up to 50MB, with a 100MB limit for registered accounts, no subscription required.
Can I convert the file back from PLY to BREP afterward?
Only what PLY 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.
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 3D scanners and scan-processing software either unless you plan to open or edit the PLY result afterward.
