alt Hacker NewsOpenSCAD isn't a CAD tool, IMO. It does nothing at all to aid your design. It barely even helps describe it in any abstract way.
It is a useful tool for programmatically describing either very simple or heavily geometric objects. For everything else it's the wrong tool.
I'd put it this way: CAD = Computer-Aided Design, i.e., software that assists in the creation, modification, analysis, or optimization of a design.
OpenSCAD clearly qualifies because it creates precise 2D/3D models; supports parametric modification; enables reproducible designs; produces manufacturable geometry (STL, DXF, etc.). The fact that it is code-based does not disqualify it. By the same logic, CadQuery, SolidPython, or FeatureScript would also not be CAD - which is not a position held in engineering practice.
