What is BenchCAD?
What BenchCAD measures and how its scores work.
BenchCAD is a benchmark that decomposes CAD capability into matched tasks, including Vision2Code, which requires models to generate CadQuery code from multi-view renders.
The Vision2Code task is scored by voxel IoU against the reference geometry, reported as a ratio.
Scores are shown in ratio. This benchmark is not independently verified and has an evidence level of B.
