| 摘 要： | 为了解决异构CAD协同设计中的一维拓扑元素匹配问题,在对其进行分类讨论的基础上,提出了一种新方法.首先在源CAD系统中,获取建模操作所弓l用的一维拓扑元素,并利用合并算法将这些拓扑元素进行合并,合并条件为:同类型、相邻接且合并所得的拓扑元素类型与原类型相同或相近.然后在目标CAD系统中,通过匹配算法为合并后的每个一维拓...

| Abstract: | To solve the one-dimensional topological entity matching problem in collaborative design among heterogeneous CAD systems,a new approach based on classification is proposed.First,in source CAD system,the one-dimensional topological entities used by modeling operation are acquired and combined by the combining algorithm.The combining conditions include: the topological entities to be combined must have the same type and be adjacent;the type of the combined topological entity is the same or similar to the prim... |
