OmniCAD - Shape Accuracy: leaderboard

OmniCAD (Pennsylvania State University and Shanghai Jiao Tong University, 2026) evaluates vision-language models on assembly-aware 3D spatial reasoning, reconstructing component poses of robotics CAD assemblies from color-by-component views. Shape accuracy is the share of components whose per-component Chamfer distance to the ground-truth mesh is below 10mm, in percent, higher is better.

Metric: PA (%; share of components whose per-component Chamfer distance to the ground truth mesh is below 10mm; over OmniCAD component-level CAD assembly generation; color-by-component views input (ColorView)). Source: arxiv.org. Saturation forecast: Not forecast. 9 models tracked.
