摘要
针对发动机零件展开了基于特征的参数化实体造型研究 ,探讨了其实现方法 .参数化方法使用户构造几何模型时可以集中于概念和整体设计、充分发挥创造性、提高设计效率 ;基于特征的技术为设计者提供符合人们思维的设计环境 .把参数化方法和基于特征的技术有机地结合起来进行实体造型将极大地提高设计效率 .用AutoLISP语言对AutoCAD1 4进行了二次开发 ,建立了基于特征的参数化发动机零件实体造型系统 .系统包括 :发动机零件特征库 ,发动机零件模型库和用户界面 .
Feature based parametric solid modeling is studied for parts of engine. By this parametric method, customers can concentrate on the conception and the whole design when they construct geometrical model, exerting creativity and improving efficiency. Feature based technology supplies designers with designing surroundings in accordance with thoughts of human being. Feature based solid modeling increases design efficiency. AutoLISP language is used to develop AutoCAD14 and establish a feature based parametric solid modeling system. The system includes engine part feature base, engine parts model base and customer interface and provides fast, convenient supports to designers.
