Mesh Inspector
Inspect triangle count, dimensions, open edges, duplicate points and surface direction in a 3D mesh.
Workflow type: Mesh inspection report. Status: Functional. Expected result: Inspection report. Available action: Inspect mesh.
What this 3D tool provides
Inspect OBJ, STL, PLY and GLB mesh dimensions, triangle count, open edges and common geometry issues online.
- Mesh Inspector brings OBJ, STL, PLY, GLB input and the listed JSON report outputs into one review sequence.
- Use the before-and-after labels for orientation, then confirm the selected file with the result guidance and format notes below.
- Accepted input: OBJ, STL, PLY or GLB mesh.
- Available controls: Treat each coordinate as, Highlight open edges, Show surface direction.
- Review geometry counts, bounds and detected conditions. A JSON inspection report is available only when the report is created.
How to use Mesh Inspector
- Choose a supported file — Choose OBJ, STL, PLY or GLB mesh from your device.
- Review settings — Review the available controls: Treat each coordinate as, Highlight open edges, Show surface direction.
- Review and download — Review the measured result and preview before downloading an available export.
Preview and result review
Use a mechanical bracket with small mesh defects to make open edges and surface direction easy to spot.
- Before example: A mechanical bracket mesh containing carefully placed geometry issues
- After example: The same bracket with open edges and surface direction highlighted
Mesh inspection report: Review geometry counts, bounds and detected conditions. A JSON inspection report is available only when the report is created.

Frequently asked questions
What does Mesh Inspector do?
It summarizes mesh size and complexity, labels raw coordinate dimensions with the unit you choose, then highlights common geometry conditions that deserve review.
Which files does Mesh Inspector support?
OBJ, STL, PLY and GLB mesh files can be inspected; scene-only objects without triangle geometry are ignored.
Is my 3D file uploaded?
Supported file contents stay on this device while the selected tool runs; site analytics and the assistant are separate. The selected file is not uploaded for the supported processing workflow.
What should I review after using Mesh Inspector?
Automated checks are a first pass. Confirm scale, print tolerances, intended openings and visual appearance in the destination application.
