Isn't CadQuery more professionally than OpenSCAD close to traditional CAD / mechanical engineering workflows. Not sure which model (ChatGPT, Gemini, and Claude Code) is better for CadQuery code generation?
It is, but they have different use cases. CadQuery uses a geometry kernel that does boundary representation, which you need for path generation for modern manufacturing tooling. OpenSCAD produces a standard mesh representation (i.e. triangles), which is insufficient for cutting and subtractive manufacturing, but often fine for additive manufacturing (3D printing).
