About this 3D viewer
Inspect a compatible BREP or BRP CAD file after local browser tessellation. The inspector reports mesh groups, vertices, triangles, and preview dimensions for a lightweight exchange-file review.
BREP files from FreeCAD, OpenCascade, and CAD workflows
Preview compatible BREP geometry in a current Windows, macOS, or Linux browser after export from FreeCAD, OpenCascade-based software, or a CAD exchange workflow. The page tessellates a display mesh locally; it is not an editor or exact BREP topology validator.
How to use this BREP viewer
- Sign in and unlock BREP tools once.
- Upload a compatible .brep or .brp file.
- Review tessellated geometry statistics before web export or a deeper CAD workflow.

BREP viewer FAQ
Does BREP Inspector validate original CAD topology?
No. It reports the local tessellated preview rather than exact CAD topology, PMI, assemblies, or manufacturing validity.
Does it edit the source BREP file?
No. Compatible geometry is processed locally only for preview and inspection.
Can I view a BREP file from FreeCAD or OpenCascade?
Yes, for compatible geometry. The browser preview is useful for visual review, while FreeCAD or a CAD tool is still needed for exact topology, editing, and engineering validation.
What file extension does BREP use?
This tool accepts the compatible BREP extension shown in the upload area. Use the dedicated format viewer when a file has a related extension or an application-specific variant.
Can I use this BREP viewer on a phone?
The page can be opened on mobile browsers, but a desktop browser is usually more practical for large files and detailed orbit, zoom, and inspection work.
Do I need to create an account to preview a BREP file?
Yes. Sign in first, then unlock this BREP tool once for $1.90. VIP members can also access the viewer.
