UVTran: Accurate Hole-Filling Parameterization with Transformers

In three linesUVTran, a transformer-based framework, solves N-sided hole filling in CAD by predicting an auxiliary projection surface via cross-attention biased toward nearby control points, voxelizing coordinates, and progressive-resolution training. On benchmark, it improves tolerance-satisfaction rate by 12% over industrial and academic baselines while producing fairer trimmed surfaces.
