RetroCAD3DBETA
A full parametric 3D CAD tool that runs entirely in the browser — sketch, extrude and fillet real solid geometry, with a proper feature tree. No installs, no licences.
What it can do
- ✓Sketch on any work plane or solid face
- ✓Extrude, cut out and fillet real 3D solids
- ✓Full feature tree — edit and reorder past steps
- ✓Runs entirely in the browser, powered by a real CAD kernel (OpenCascade)
A genuine parametric 3D CAD tool, built for the classroom and running entirely in the browser — no installs, no licences, nothing to configure. Students sketch on work planes or solid faces, then extrude, cut out and fillet real solid geometry using the same kind of CAD kernel professional tools are built on. Every step lands in a feature tree they can edit and reorder, so the model stays a live design, not a dead end.
