基于知识的智能CAD系统设计

The Development of Knowledge-Based Intelligent CAD Systems

通过对工程智能CAD系统及其设计模型的研究，提出了工程智能CAD系统设计理论：规划控制下的二阶段设计理论，论述了基于这一理论的工程智能CAD系统设计方法、设计对象的模型构造方法和智能CAD系统中各类工程设计知识的应用。并已将这一方法成功地应用于工程智能CAD系统的开发实践。

Based on the research of intelligence CAD and it's model, a design theory on twostage under the planning control is Put forward. With this theory, the intelligent CADtechnology, the key technology to design object modeling and the application of engineeringknowledge are studied. So far, this theory has been successfully used in the development of several engineering intelligent CAD Systems.
