基于特征技术的液压管道布置CAD技术

CAD technique of hydraulic piping layout based on feature technology

液压CAD技术中，管道布置CAI）是研究与开发的热点。本文运用基于特征造型的CAD／CAP集成技术，应用面向对象的设计方法，基于现有的CAD几何实体造型模型，实现了液压系统管道布置和加工工艺的集成。

The hydraulic piping layout is a key techniquewhich has not been fully studied in hydraulic system design. Basedon the feature modeling technology, we utilize object-orientedmethod to develop a CAD/CAPP software for hydraulic piping layout on the basis of existing CAD geometric model.
