摘要
通过分析现有参数化 CAD系统在知识表达方面不足的 ,提出了几类新的知识表示方法 ,并用一种基于约束网络的技术 ,实现了知识约束的智能化求解。集成了该功能的
By analyzing the deficiencies of knowledge representation of present 3D parametric CAD systems, a series of new techniques for knowledge representation are proposed in this paper to express knowledge in the domains of design. Further, a new technique based on constraint network is put forward to solve constraint reasoning. The new CAD system integrating the above techniques can satisfy requirement for parametric product modeling based on engineering knowledge.
