Teng Hong-fei · Computer Engineering and Applications Journal · 2009
The interference calculation of irregular solid model is performed frequently when solving the complicated layout optimization problems based on Pro/E.The fast interference calculation becomes to the bottleneck of the layout optimization.Therefore,a solid model simplification approach is proposed by Pro/E secondary development.The method simplifies the solid model into bilevel model:The first level is the bounding box,while the second level is composed of regular geometry models.The experimental results show that,the proposed method outperforms the bounding box,the octree method and the conventional human-computer interactive method in form of the interference calculation efficiency and the calculation precision.
