基于对象理论的工程图纸管理系统关键技术研究

A Study on Some Key Techniques in the Management System of Engineering Drafting Based on Object-Oriented Theory

工程图纸管理是CAD/CAM的重要组成部分 在应用面向对象理论的基础上 ,讨论了工程图纸管理的几个关键技术问题 :机械产品图纸目录树的自动生成 ;AutoCAD内部多文档 -视界面的实现 ;ODBC(OpenDataBaseConnectivity)技术在工程图纸管理中的应用 ;零部件类 (Class)在图纸管理中的应用 研究结果表明 ,基于面向对象理论和技术的CAD/CAM 。

The management of engineering drafting is a very important part of CAD/CAM. Based on the application of object-oriented theory, several key problems are discussed on the management of engineering drafting as follows: how to generate the tree view of mechanical products automatically; how to realize MDI inside AutoCAD; the application of ODBC in the management of engineering drafting; the application of work part class in the management of engineering drafting . The study shows that CAD/CAM based on the object oriented theory and technology is a very important direction for the development of CAD/CAM.
