基于ECAD平台的三维配管设计软件开发研究

COMMENTS ON IMPROVING THE MODELING OF PIPING DESIGN SOFTWARE

本文针对我国化工领域实现配管设计的实际需要，提出在三维管道建模过程中模型的拓扑定义与几何造型分步实现的思想，并简要介绍了在ＥＣＡＤ平台上开发三维管道设计系统的方法和关键技术。

Labelled line segments with recorded coordinates of their keypoints are used for pipeline layouts. 3D models of the plant are constructed procedurally by inserting elbows,T-connections, valves, reducers, etc. at the corresponding keypoints. Shading pictures, section views or line drawings can be generated as required. Measures to simplify geometric modeling and reduce the cost of software development are discussed.
