CADEngBench: It Looks Like CAD, but Does It Work? Evaluating Parametric Design, Assembly Reasoning, and Physics Simulation
CADEngBench, a layered benchmark of 600 parametric tasks and 120 assembly pairs, shows current AI models edit supplied CAD far more easily than they generate it, and rarely match reference physics or recover exact assembly joints.
