协同设计环境下的产品造型系统

协同设计对于传统的产品造型系统有了更进一步的要求。本文总结了协同设计环境下的产品造型系统的特点，提出了一个协同产品造型系统的框架，对系统的造型方法以及产品模型的表示方法作了讨论，并对系统如何使产品模型具有动态的结构及表示以满足不同设计小组的需求作了说明。最后，文章对造型系统中约束的处理以及我们目前和今后所做的工作进行了简要的阐述。

TheProductModelingSystemin Cooperative Design Environment

Cooperative design gives more requirements of traditional product modeling system. This article summaries the character of product modeling in cooperative product design, puts forward a frame of cooperative product modeling system, discusses the methods of modeling and the data expression of product model. Then the article explains how system makes product model have the dynamic structure and expression to meet the request of different design groups. At last, the disposing of constraints in modeling system and our present and future works are elaborated briefly.
