for everyone

write CAD models in Javascript

I mean good for anyone who's into this - for me, I'll stick with openscad though ( https://openscad.org/ ).

Same thing but with a dedicated language dedicated to 3D modeling, algebraic approach to shapes and a long history and track record.

Here's a plugin for Blender that works like Grasshopper for Rhinoceros3D: sverchok (which is Russian for grasshopper).

I'd rather avoid algorithmic modeling in JavaScript or in a browser.
