PDM系统中三维图纸版本管理的研究

Study on Version Management of Three-dismension Drawing for PDM System

在目前的版本管理系统中,把文件作为管理对象的核心,管理产品零件某个版本相关的各种数据,包括CAD模型和各种文档等。版本管理普遍针对二维图纸。文章分析了产品数据管理系统中版本数据的特点,首次针对三维图纸的整体特性提出了适合中小型企业实际情况、操作简单实用的版本管理策略及其版本管理实现技术,通过在实践中的应用,证明它是有效的。

The file is regarded as the key of the management object of the current Product Data Management which manages all kinds of data,contains CAD models ,documents and so on. Version management is aimed at two-dismension drawing usually. This paper analyses the characteristics of version data in PDM,and suggests a new Version Management strategy for the three dismension drawing according to their integration, This strategy has been implemented in a PDM system and used by small and medium-sized companies. The feed back from users indicates that the strategy is effective.
