I've been gearing up to submit agentcad to cadbench which is an eval set for CAD models.
As I've been going through that, I've found some error scenarios where everything "looks" right to me and to the agent but is actually off by a small amount here or is missing a specific shape over there.
Give your coding agent the ability to design real, manufacturable parts.
Hand Claude Code or Codex a prompt, a sketch, or image. It writes build123d or CadQuery scripts, then runs agentcad to check its own work, catching broken code, confirming the geometry is watertight and dimensionally correct, and rendering it from every angle so your agent fixes its mistakes before you ever see them.
You get back an interactive viewer plus STEP / STL / GLB files — ready to inspect, edit, or print.
