Abstract: This paper introduces the research of a general engineering information graphic marking system. Using object-oriented technology, a system model is build and described by unified modeling language, then, the graph transformation problem is resolved and an applied instance based on the control of Autodesk DWF viewer is provided. The technology can be widely used in the pos-processing function of engineering calculation software.

Key words: Graphic marking, Object-oriented modeling, Unified modeling language(UML), Software development

摘要： 研究了通用工程信息图形化标注子系统的设计方法，采用面向对象技术建立了系统模型，使用UML标准描述了模型结构，解决了图形变换中的关键问题，基于Autodesk DWF Viewer控件给出了应用实例。该方法可普遍应用于工程计算软件后处理功能的实现，使软件的计算结果对用户的反馈更加形象、直观，具有一定的工程应用价值。
