About TOK CAD
TOK CAD is parametric 3D CAD that runs in your web browser: constrained sketches, an editable feature history, multiple bodies, assemblies, drawings, and STEP import and export. The geometry kernel runs on your own computer, so your models are not uploaded to model them.
It is run by Tokeena Engineering at tok-share.com/cad.
