CadQuery is an open-source Python library for building 3D CAD models | Hacker News

A Hacker News post highlights CadQuery and build123d for Python-based 3D CAD prototyping.

The user described a cosplay helmet workflow that started in Blender, then used Python scripts to add thickness, split parts, and refine the model for 3D printing.

They said AI can help with snippets, but it is not yet reliable for generating complete CAD scripts end to end.

The post argues that code-driven modeling can be more flexible than sketch-and-constraint workflows, especially for rapid iteration and fabrication.
