CADDesigner Automates CAD Modeling
量子位 · wechat · 2026-07-12
A Zhejiang University team proposed CADDesigner, a multimodal CAD modeling agent designed to combine LLMs, agents, and traditional geometry engines. It helps designers translate text and sketch intents into parametric CAD models.
Key designs include:
- Simultaneous input of text descriptions and sketches;
- ECIP, a script paradigm for LLMs that ensures consistency across APIs, parameters, and behaviors, reducing trial-and-error in code generation;
- A constraint system that only defines rules without directly participating in geometric calculations, minimizing complex computing errors;
- Attaching ID-like tags to parts to solve object selection difficulties during modeling;
- Error feedback providing location, type, cause, and repair suggestions, complete with automated checking scripts.
The related research has been published in Computer-Aided Design, and the repository is now public.
