摘　　要：分析三维CAD中基本数据类型,并抽取面向管理的结构化信息;定义了数据间的关系类型及数据生命周期状态;给出数据约束和关联定义.结合CAD数据的生命周期管理,提出关联数据在进行出库、入库、发布等方面的操作时,相关数据进行自动更新的规则.针对CAXA实体设计系统给出管理数据模型,并在SMARTEAM平台上实现.Through analyzing the fundamental data types in 3D CAD, the structured management information is extracted and the constraining relationship and associativity among these data types are defined. In view of the data lifecycle management （Check in, Check out, release, etc. ）, operation rules are designed for the automated update of associative parts data. This helps to preserve the original design intent or specifications during engineering changes. At the same time, associative management provides instructions for process and knowledge management. A special data model is defined for CAXASOLID, and the system integration is accomplished on SMARTEAM. Association between 3D model and 2D drawing is maintained in PDM, and synchronized check in and check out keep the consistency of 3D and 2D.
