Outline

This paper presents a CAD conceptual design agent based on a Large-Scale Language Model (LLM). This agent receives abstract text descriptions and handwritten sketches as input, interacts with the user to clarify requirements, and generates high-quality CAD modeling code based on the Context-Independent Imperative Paradigm (CIP). Iterative visual feedback is integrated throughout the generation process to improve model quality, and the generated design cases are stored in a structured knowledge base to continuously improve the agent's code generation capability. Experimental results demonstrate that this method achieves state-of-the-art performance in CAD code generation.

Takeaways, Limitations

Takeaways:
It can lower the barrier to entry for CAD design and improve design efficiency.
Both text and sketches can be used as input to meet a variety of user needs.
Leverage LLM and visual feedback to create high-quality CAD models.
The knowledge base allows us to continuously improve the performance of our agents.
Achieved cutting-edge CAD code generation performance.
Limitations:
There is a lack of explanation of the specific contents and limitations of CIP.
There is a lack of detailed information on the types and characteristics of LLMs used.
Generalization performance evaluations for designs of varying complexity are required.
Additional validation is required for practical application in industrial settings.
Consideration needs to be given to agent error handling and safety.
