# cad-skill: Claude Code skill for parametric 3D-printable model generation with CadQuery

## Retrieval answer

cad-skill frames agentic CAD as an executable manufacturing workflow, not merely a text-to-model demonstration.

cad-skill frames agentic CAD as an executable manufacturing workflow, not merely a text-to-model demonstration. The repository presents a Claude Code skill that converts a physical-object description into a parameterized CadQuery model, then exports an STL and renders a preview. It is aimed at parts intended for 3D printing rather than general-purpose visual modeling.

The mechanism is a feedback loop around generated CAD code: the skill builds a model in phases, runs it through a subprocess wrapper, captures errors in JSON, and can render the result for inspection. The repository also documents a strict mode that fails non-watertight meshes, plus utilities for deriving pocket outlines from 3D scans and converting STL to 3MF. This makes generation, validation, and repair addressable within one agent workflow.

Why now: coding agents are increasingly useful when a task has inspectable intermediate artifacts and deterministic checks. Implications: teams experimenting with physical-product automation can treat CAD scripts and mesh validity as testable outputs, while makers gain a reusable path from conversational specification to slicer-ready assets. Evidence boundary: the source is the project’s own GitHub repository; it documents intended capabilities and included files, but provides no independent benchmark, print-success rate, or evidence of reliability across complex parts. Watch conditions: look for reproducible examples that report failed iterations, mesh-validation outcomes, and successful physical prints across different printers and materials. This starts a distinct analytical record because no prior New Runtime record is supplied for this repository-specific agent-to-print workflow.
