Six AI models, five CAD platforms, 18 real-world engineering drawings. CAD Arena evaluates how agents turn drawings into editable CAD designs.

Can AI build editable CAD? LLMs are becoming capable at understanding and creating in CAD. To be maximally useful to engineers, the agents can live in the platforms where engineers already work, building proper sketches, features, and parameters that people can inspect, understand, and change. We introduce CAD Arena, an evaluation of how well AI agents reconstruct real parts as CAD models with human usable feature trees. This benchmark differentiates from others by including: Real-world parts. Tasks use engineering drawings licensed from the manufacturers that produced the parts.…
