摘　　要：工程图是进行工业生产和技术交流的重要文档,而在三维CAD系统中制作标准化的工程图比较烦琐.通过分析UG和ProE等系统工程图模块功能的不足,充分考虑不同平台二次开发的差异,借鉴成熟的软件体系和先进的开发工具,提出了一个通用的面向异构CAD平台的工程辅助绘图软件框架;并详细讨论了物理模块部署、逻辑对象构造和实例维护、工程随动约束管理以及产品装配模型访问等关键技术;研究开发了实用系统并在企业中得到应用.The engineering drawings are important documents for industrial manufacture and technical exchange, but it is very difficult and tedious to make a standard drawing in 3D CAD systems. Through analyzing the functional shortage of engineering drawing module and well considering the differences of secondary development on different 3D platforms, the paper presents a general computer-aided engineering drawing software architecture for heterogeneous CAD systems based on ready-made software architecture and advanced development tools. Several key technologies are discussed in detail, including deployment of physical modules, construction of logical objects and maintenance of their instances, management of engineering constraints of attached entities which follow their host entities, access of product assembly model, etc. A software package based on the method mentioned above is developed and used in practice.
