利用STEP的设计意图信息交换

摘要

The standard for the information exchange of design intent is the base for information exchange among heterogeneous CAD systems. Discusses the contents, schema of representation and implemented neutral file format of newly published parts of the international standard ISO 10303. The characteristics, mapping model and key technology for information exchange of design intent are discussed. A neutral information exchange mode and an approach to mapping design intent information among CAD systems are presented. By means of neutral file based on AP203 ,the information exchange of design intent has been realized. At last an example of data exchange based on standard for the information exchange of design intent is given.%设计意图信息交换标准是异构CAD系统之间设计意图信息交换的基础.对ISO 10303(STEP)标准最近公布的关于基于特征的设计意图信息交换标准的内容、表达模式及实施的中间交换文件格式进行分析;对设计意图信息交换特点、交换映射模式,以及交换过程中涉及的主要关键技术进行探讨;通过基于AP203交换协议的中间物理交换文件,实现设计意图信息交换,最后给出一个基于设计意图交换标准的零件特征参数化模型数据交换实例.
