PDM图文档信息自动获取方法研究与实现

Study and Implementation on Extracting Information of Graphics and Documents Automatically for PDM

图文档管理是产品数据管理系统中的基本功能 ,为了实现图文档信息的自动入库 ,需要实现CAD图档信息的自动读取。通过分析DXF文件的格式 ,得出读取CAD图档的标题栏信息的方法 ,然后采用Java技术 ,实现了这一功能 ,并且应用在基于Web/CORBA的PDM系统中 。

The management of graphics and documents is the basic function of produ ct data management system. In order to transfer information into database automa tically, it is necessary to implement automatic extraction of information from h eading table of CAD drawing. In this paper, the format of DXF files is first an aly zed, and the solution of extracting information from DXF files of CAD drawing is got by of means Java technology. In the end, it is applied to the PDM system ba sed on the Web and CORBA technology and the expected aim is obtained.
