MAC (Multi-Agent CAD)

Turns text into printable STEP/STL geometry through four LLM agents on a LangGraph state machine: requirement parsing, geometric planning, code generation, then autonomous QA and repair. Every intermediate artefact stays human-auditable. On a 141-feature suite it cuts tokens 103.9M to 896K (116x) and API calls 1,307 to 50, while pass rate rises 97.9% to 99.3%. MIT, 495 stars.
