Questions
Which formats can I open?
All 20 input formats the converter supports, including STEP and IGES, which are tessellated by Open CASCADE before display.
Do I need a powerful machine?
Any laptop with WebGL handles models up to a few million triangles. Very heavy scans still open, but orbiting gets choppy once the triangle count passes what your GPU can push at 60 frames per second.
Can I share a link to a model?
No, and that is deliberate. Since the file never leaves your browser, there is no URL that could point at it. Convert to GLB and host the file yourself if you need to share.
