Online STEP / IGES / STL viewer

Open and inspect supported STEP, IGES and STL models in the browser.

How to use

Files are processed on your device and are not uploaded. Up to 25 MB per file. SVG: 1 MB total, at most 50 parts.

Choose a file or open the example.

How to use

Open a STEP/STP, IGES/IGS, STL, OBJ, OFF or PLY file. Rotate and zoom the model.

Example calculation

The STL example shows a tetrahedron.

Calculation limits

Limits: 25 MB per file, 500,000 triangles per model and 90 seconds per operation. STEP/IGES surfaces are tessellated. Geometry and supported face colors are preserved; textures and parametric CAD metadata are not. Complex models may exceed memory limits. WebGL is required. STL has no unit metadata; preserve source units. The STEP/IGES decoder is loaded from a CDN when needed.
