SOTA (Mesh2CAD) on BenchCAD, DeepCAD, Fusion360, MCB. Beat Claude Opus/Mythos 5, GPT 5.6 Sol, Kimi K3 and any other models!!! And it’s full open-source

Our contributions are: 1. CADENA (Spanish for “chain”) – stepwise reverse-engineering model specific for CAD; 2. CADENA-Bench – a benchmark of 3396 real mechanical parts in six part families which; 3. GMS (btw, my contribution;))– surface-matching metric, made specific for CAD reconstruction, not just for 3D reconstruction like Chamfer Distance, IoU.
