CADENA-Bench (anonymous copy for review)
Benchmark accompanying an anonymous ICLR 2027 submission, provided for double-blind review only: 3396 real mechanical parts drawn from MCB, TMCAD and CADNET, stripped of trivial and duplicate geometry and grouped into six part families.

Fields
| Column | Contents |
|---|---|
part_id |
Stable identifier; evaluate.py matches predictions on it |
family |
One of the six part families |
mesh |
The target mesh, raw STL bytes |
mesh_file |
Target mesh filename |
image |
The eight target views tiled into one image |
prompt |
The chat prompt used at inference |
The 108 meshes byte-identical to a mesh in the reinforcement-learning training corpus are removed, so this benchmark and the RL training set do not intersect.
