  4. Having played around with this a bit, I recommend using https://github.com/CadQuery/cadquery as the CAD language instead. I'm pretty sure it could even transpile to OnShape / Solidworks models as well, though it might require some funky…

  15. https://github.com/CadQuery/cadquery : > CadQuery is often compared to OpenSCAD. Like OpenSCAD, CadQuery is an open-source, script based, parametric model generator. However, CadQuery stands out in many ways and has several key advantages:…

  18. I agree with you. That's why in the past I made this issue: https://github.com/CadQuery/cadquery/issues/153 The developers don't seem to be receptive. But fortunately a nix flake exists: https://github.com/marcus7070/cq-flake Takes ages to…

  21. …There is also CadQuery, which claims to have fundamental technical advantages over OpenSCAD: https://github.com/CadQuery/cadquery I've tried CadQuery and had a rough time of it. I haven't used OpenSCAD at all though, so I can't compare.

  33. …but these mesh-based tools can produce files usable by CNC machines. I eventually found CadQuery ( https://github.com/CadQuery/cadquery ) which can create non-mesh STEP files. It’s a lot rougher then OpenSCAD but usable.
