CADEngBench - Executable CAD (L0): leaderboard

CADEngBench (MBZUAI, 2026) evaluates multimodal models as CAD engineers. In the zero-to-CAD task a model turns an engineering brief, reference views, parameters and requirements into an executable CadQuery program; L0 is the percentage of 300 parts whose program runs, builds a valid B-Rep solid and survives STEP export and re-import, higher is better.

Metric: Executable CAD rate (%; share of 300 parametric part tasks (159 BenchCAD, 141 Fusion 360) whose brief, reference views, parameters and requirements the model turns into an executable CadQuery program; one response per task, no retries whose program executes, builds a valid B-Rep solid and survives STEP export and re-import). Source: arxiv.org. Saturation forecast: Around February 2027. 8 models tracked.
