An intelligent interactive system based on LLM to combine CAD API development with FEA

This paper presents an intelligent interactive system based on large language model (LLM). It aims to simplify the operation flow of CAD and FEA software and improve the efficiency of design and simulation analysis. The system uses C# and Python to develop CAD Secondarily and access LLM API locally. Build a professional database and implement the interaction between CAD and LLM. The natural language dialogue between the user and the CAD software is realized, and the design guidance and optimization suggestions are provided. Taking the design of the end mechanism of fruit picking robot as an example, the application effect of this system is demonstrated. The results of the case show that the system can effectively improve the efficiency of design and simulation analysis, and improve the design quality, and has a broad application prospect.
