Powerful Features
Complete Geometry Analysis
Get comprehensive statistics on your 3D model including vertex count, face count, edge count, bounding box dimensions, and accurate volume calculations. Our real-time analysis processes models instantly to give you the metrics you need for optimization decisions. Perfect for understanding model complexity before web deployment or identifying issues that could impact performance.
Visual Error Detection
Automatically scan for and highlight common geometry problems including flipped normals, non-manifold edges, open boundaries, and degenerate faces. Visual overlays show exactly where issues exist on your model, making it easy to locate and fix problems in your 3D software. Essential for ensuring models are watertight and ready for 3D printing or game engines.
One-Click Auto-Repair
Fix common geometry problems without leaving the browser. Repair flipped normals that cause shading artifacts, remove degenerate faces with zero area, and merge close vertices to clean up mesh topology. Each repair operation works directly on the model and updates the analysis in real-time. Export the repaired model or continue inspecting with confidence that basic geometry issues are resolved.
Auto-Scale Detection
Automatically detect when models are scaled incorrectly — too large (likely in millimeters instead of meters) or too small (possibly centimeters when meters expected). Get instant warnings with clear explanations and one-click fixes to apply the correct scale factor. Essential for 3D printing workflows, AR placement, and ensuring CAD exports maintain proper real-world dimensions.
Web Readiness Score
Receive an instant 0-100 performance score that evaluates your model for web and mobile deployment. Our scoring algorithm analyzes polygon count, texture sizes, draw calls, and mobile compatibility to give you actionable insights. Know exactly how your model will perform before publishing to websites, AR experiences, or e-commerce platforms.
Measurement Tools
Measure point-to-point distances, edge lengths, and angles between faces directly on your 3D model in real-time. Click any two points to get precise measurements in your preferred units. Perfect for verifying dimensions match CAD specifications, checking clearances, or ensuring scale accuracy before production or printing.
Exportable Reports
Generate comprehensive inspection reports in multiple formats including detailed text summaries and professional PDF documents. Reports include all geometry metrics, detected errors with severity levels, web readiness scores, and actionable optimization recommendations. Save reports for documentation, share with team members, or include in project deliverables.

Why Choose Our 3D Model Inspector?
Our 3D Model Inspector is a comprehensive browser-based validation tool for analyzing and optimizing 3D assets. It delivers instant geometry analysis, error detection, and web readiness scoring without uploads or installs. Whether you're preparing models for game engines, validating STL files for 3D printing, or optimizing assets for WebGL delivery, the inspector provides the actionable data you need to ship with confidence.
The geometry analysis system goes beyond simple polygon counting. You get detailed breakdowns of vertices, faces, edges, bounding box dimensions, and volume calculations — computed in real-time as you load the model. These metrics help you understand complexity at a glance, spot optimization opportunities, and plan LOD or mesh simplification strategies that meet mobile and headset budgets.
Detect Errors Before They Cause Problems
Geometry errors can derail production. Non-manifold edges break slicers, flipped normals cause shading artifacts in AR/VR, and open boundaries can fail booleans in CAD. The inspector scans your model in seconds and highlights issues with overlays so you can fix problems before they impact the workflow. It checks flipped normals, non-manifold edges, open boundaries, degenerate faces, and duplicate vertices.
One-Click Auto-Repair for Common Issues
Skip the round-trip to your 3D software for basic geometry fixes. The inspector's auto-repair feature corrects flipped normals that cause dark faces in renders, removes degenerate triangles that break mesh processing, and merges vertices that are nearly coincident. Each repair runs in milliseconds and updates the analysis immediately so you can verify the fix before exporting.
Automatic Scale Detection and Correction
Incorrect scale is one of the most common problems when exchanging 3D files between tools. The inspector automatically detects when models are suspiciously large or small — a sign that units were misinterpreted during export. You get a clear warning explaining the likely issue and a one-click fix to apply the correct scale factor. Essential for 3D printing, AR placement, and architectural visualization where real-world dimensions matter.
Web Readiness Scoring for Optimal Performance
Publishing 3D models to websites, AR experiences, or e-commerce platforms requires careful optimization. Our web readiness scoring evaluates polygon count, texture resolution, draw calls, and mobile compatibility to provide a 0-100 score with specific recommendations. Use it to validate assets before shipping to WebGL viewers, XR experiences, or product configurators.
Professional Measurement Tools
Accurate measurements matter in manufacturing, architecture, and product design. Built-in tools let you measure distances, edges, and angles directly on the model in metric or imperial units. Confirm CAD exports maintain scale, check clearances between parts, and validate 3D scans before production or quoting.
Comprehensive Reports and Documentation
Document results with exportable reports in multiple formats. Generate text summaries or PDF reports that include geometry statistics, detected errors, readiness scores, and measurements. Use reports to track iterations, share fixes with teammates, or satisfy QA and compliance requirements.
Complete Privacy and Security
Your 3D models are valuable IP. The inspector runs client-side using WebGL and WebAssembly, so files never leave your device. This protects confidential CAD data, unreleased game assets, and proprietary product designs while delivering fast, desktop-quality performance.
Frequently Asked Questions
Is my model data secure?
Yes. Everything runs in your browser using WebGL and WebAssembly, so your meshes never upload to our servers and stay on your machine.
What file formats are supported?
You can inspect GLB, GLTF, STL, OBJ, FBX, PLY, 3MF, and USDZ files. Drag in individual assets or zipped bundles with textures.
Can I use this for 3D printing validation?
Yes. The inspector flags non-manifold edges, thin walls, flipped normals, and open shells so you can fix issues before slicing or printing.
Do I need to create an account?
You can run inspections for free without logging in. Create an account when you want to save reports, track history, or unlock team features.
Is there a file size or polygon limit?
The browser comfortably handles models up to a few million triangles. If a model is too heavy, the app prompts you to decimate or split it before re-running checks.
Can I switch measurement units?
Yes. Toggle between metric (mm, cm, m) and imperial (in, ft) units at any time. Measurements update instantly so mixed teams stay aligned.
How do I share inspection results?
Export a PDF or JSON report directly from the inspector. Reports include stats, screenshots, readiness scores, and prioritized fixes you can send to clients or teammates.
Does the tool work with animated or rigged assets?
Animated meshes, skeletons, and skin weights load just fine. You can review clip counts, bone hierarchies, and mesh density before moving into a game engine or DCC.
What issues can auto-repair fix?
Auto-repair handles flipped normals (which cause shading artifacts), degenerate faces (zero-area triangles), and can merge close vertices to clean mesh topology. One click applies the fix directly to your model.
How does scale detection work?
The inspector analyzes bounding box dimensions and flags models that appear incorrectly scaled — for example, a car-sized object measuring only 2mm. You get a warning with suggested scale factors and can apply the fix instantly.
