Abstract: Freeform surface features (FFSFs) extraction is one of the key issues for redesigning and reediting the surface models exported from commercial software or reconstructed by reverse engineering. In this paper, a coarsetofine ...

Abstract: Laplacian based model editing is one of the most popular shape modification methods for product design. However, most existing Laplacian based methods suffer shape structure and saliency feature distortion, which limits ...

Abstract: Identifying and eliminating conflicts and redundancies between geometric constraints is crucial for effective constraint resolving in engineering design. This research proposes a graph-based conflict detection and resolution ...
