CADENA: Stepwise CAD Reverse Engineering

CADENA reconstructs a 3D mesh as an editable parametric CAD program one operation at a time, comparing the target mesh with the current predicted geometry after every step. The authors also introduce CADENA-Bench for evaluating reverse engineering across mechanical-part categories. According to the supplied abstract, CADENA outperforms prior methods on CADENA-Bench as well as DeepCAD, Fusion 360, and MCB. Code, model weights, and benchmark data are linked publicly, but the provided summary contains no numerical results, and the future-dated arXiv record could not be independently validated here.
