MIT engineers have introduced an artificial intelligence system designed to operate computer-aided design (CAD) software much like a human user, turning simple 2D sketches into fully modeled 3D parts by "clicking" through the interface. Announced on November 19, 2025, the research centers on a virtual tool and dataset called VideoCAD, created to ease the steep learning curve that often keeps students and early-career engineers from becoming proficient in professional CAD applications. Instead of rewriting CAD from scratch, the team teaches an AI agent to drive an existing commercial CAD program via mouse movements, menu selections, and keyboard shortcuts, mirroring the way experienced designers work day to day.
At the heart of the project is the VideoCAD dataset, which contains more than 41,000 recorded examples of how 3D models are built step by step inside CAD software. Each example links high-level design commands such as sketching lines or circles and performing extrude operations to the low-level interface actions needed to carry...
