Based on the key technologies of data transfer in CAD / PDM, this paper proposed a two-way data attribute mapping mechanism,achieved the two-way exchange of PDM system data and CAD system data, which provide a new method for seamless integration between PDM system and CAD systems and improve the efficiency of the implementation of the PDM.%本丈针对CAD/PDM中数据传递关键技术进行研究,提出一种数据属性双向映射机制,实现了PDM系统数据与CAD系统数据的双向交换,为PDM系统和CAD系统之间实现无缝集成提供了一种新的方法,提高了PDM实施的工作效率.
