三维管路系统CAD的设计与实现

Conception and implementation of three-dimensional piping CAD

总结了三维设计应用中存在的问题 ,探讨了建立集三维设计与二维制图于一体的三维设计环境的目标以及具体实现方法 ,提出了示意模型为主、形象模型为辅的总体架构方法 ,论述了虚拟工程现场的建造、二维工程图的自动生成等技术。

Summarizes the problems in the application of three dimensional design. Discusses the goal and implementation method on the integration of three dimensional design and two dimensional drafting. Puts forward the framework in that the sketchy model takes main function and particular model is auxiliary. Depicts the skills on the construction of virtual scene and the generation of two dimensional drawings.
