Abstract
This article presents CAD2TechSpec, a novel framework for automating design processes within computer-aided design (CAD) systems by leveraging multimodal large language models (LLMs). The framework enables the analysis and generation of detailed design specifications, including the automated creation of machining process plans. Our system architecture combines 3D model rendering, dimensionality reduction techniques, and the capabilities of multimodal LLMs to produce structured JavaScript Object Notation (JSON) representations of manufacturing workflows. Experiments conducted on a big CAD model (ABC) dataset demonstrate that CAD2TechSpec significantly reduces design time while enhancing the accuracy and completeness of technical specifications. The proposed approach holds considerable promise for high-tech industries such as precision manufacturing and mechanical engineering, where efficiency and precision in design processes are critical.
