What are advantages of this compared to openSCAD or CadQuery? Specifically I ditched openSCAD for cadquery because it can't export to brep formats like STEP.
I'm not sure it's an advantage, but it's nice to see an alternative implementation of CSG. OpenSCAD depends on CGAL. CadQuery depends on CASCADE. This depends on neither as far as I can tell.
exporting true brep is not an advantage? All CNC shops I talk to require a brep based file. Software that allows you create technical drawings also require that file format.
What IDE are you using for CadQuery? I really want to get into it, but I had trouble getting the default IDE up & running. And standalone python was too troublesome to code/visualize, the feedback loop got too long, especially compared to pure UI CAD such as Fusion360
I use cq-editor[1]. For sure CadQuery and CQ-editor have a insanely sucky install experience. I never got it to work by following conda guides. I run NixOS so for me it's as installing it as a package.
