2
Tessellate & Extract Colors
Click 'Convert STEP to GLB'. Our WebAssembly engine processes the conversion entirely locally, accurately tessellating smooth CAD surfaces and preserving mesh face colors.
3
Download the GLB File
Once completed, click 'Download GLB File'. Your newly converted .glb file, ready for web applications, AR/VR, and gaming engines, will be instantly saved.
Industrial-Grade CAD Parsing
Powered by a robust OpenCASCADE (OCCT) WebAssembly engine, our converter intelligently interprets mathematically complex STEP files, ensuring flawless surface tessellation and eliminating missing mesh faces found in inferior tools.
Client-Side Privacy Guarantee
Industrial and engineering designs are highly sensitive. Unlike traditional online tools that temporarily store your assets, our STEP to GLB conversion happens completely inside your browser. Your proprietary CAD models are never uploaded to any remote server.
Retains Geometry & Colors
Converting from CAD boundary representations (B-Rep) to polygonal meshes can result in data loss. Our tool diligently extracts available face color data from the STEP model, automatically mapping it into standardized GLB object materials.
