摘　　要：通过知识约束将设计知识和参数化特征造型系统有机地联系起来,在三维CAD系统中,对工程问题和任务分解为知识项,再通过知识项到知识约束的分解,实现设计知识融合驱动的知识约束模型 最后介绍了InteSol id2This paper aims at establishing a direct driven relationship between design knowledge and present parametric feature-based modeling system. A knowledge fusion and driven approach is proposed to accomplish the knowledge constraint model which includes decomposition of engineering design task into knowledge primitives, then from knowledge primitives into knowledge constraints. Finally, the algorithm based on directional graph is introduced to solve the problem in the knowledge driven module of InteSolid2.0 system.
