Best part of 2021 for me was doing CAD again after 25 years. Using in the browser was a genuine pleasure. My last time using CAD tools was ProEngineer/ProMechanica at an internship in 1996 (Silicon Graphics workstations!)

Vague idea of sketching or rough-CADding 1 robot per week as my 2022 creative project. Bit burned out on writing, need to get back to drawing.

Pity I have no access to a deeper CAD tool chain for dynamics, FEM etc, and no good justification for paying for licenses. OnShape is free.

FWIW, I’ve been enjoying playing around with Mathematica’s recently-added support for PDE’s, which is not quite free, but remarkably affordable for all the functionality it entails— writings.stephenwolfram.com/2021/12/launch

note that on the free tier, you can’t actually own anything you create with it (iiuc)
Fusion 360 seems like a good free alternative if that matters to you
