中文摘要：

以三维CAD系统Inventor为例，探讨了CAD和PDM系统之间的数据共享和应用集成技术，PDM通过CAD的API（Add—In）获取产品设计信息，CAD通过PDM的Web服务获取产品零部件的“外部”属性，从而实现CAD和PDM系统之间的数据共享和应用集成．

英文摘要：

The integration of PDM system and CAD system needs not only transfer of prerequisite and apprehensible data but also interoperations between the two systems. Data sharing and application integration are studied between PDM and CAD in this paper, on the base of the instance of three- dimensional CAD Inventor. In which, PDM accesses the product design information through the API （Add-In） of CAD, and CAD gets the product components ＂external＂ attribute through Web service of PDM, in this way, data sharing and application integration between PDM and CAD come true.
