A benchmark for CAD reverse engineering on real mechanical parts, drawn from
MCB, TMCAD and CADNet, stripped of trivial and duplicate geometry, and grouped
into six part families so that a method's weaknesses are visible rather than
averaged away.
3396 parts. Reported per family, because aggregate scores hide exactly the
failure modes that matter: every learned method we evaluate loses roughly half
its GMS moving from sketch–extrude corpora to these parts, and the… See the full description on the dataset page:
