Pdm system can solve the problems of product data management , but the study of standardization of the product information source is rare , this paper , from the standardization of the information source , based on the analysis of main model , file naming , environment settings etc . presents the data creation standard , and implemented it as a system called ucdcs ( ug china data creation standard ) using the developing tool ug / openapi on the ug system , its using indicates that the standardization of cad data can make the data exchanging easier , information standardization can be a good foundation of pdm implementation
Pdm系统解决了产品数据管理的问题，但是对数据源的规范化却缺乏研究，本文本着信息源的规范化，从主模型、文件命名、属性输入和重用、深度备份、参考集和图层等环境设置方面出发，研究了产品数据的规范化，提出了数据创建标准，并在ug系统上使用ug openapi开发了ug规范化应用软件ucdcs ( ugchinadatacreationstandard ) 。企业的应用实践表明，规范cad数据的生成，既保证了设计各阶段数据的全相关、共享，也保证了主模型的安全，方便设计人员间cad数据的交换，提高了cad数据共享程度和cad软件使用水平，为pdm系统的有效实施规范了基础数据。
