光学仪器参数化设计软件系统（OIPS）的开发

The Development of Optical Instrument Parametric Design Software System

本文论述了ＣＡＤ新技术—参数化设计。从先进的ＣＡＤ软件出发，描述了参数化建模的基本方法及特征建模、约束建模、变量几何推理式草图设计等新技术。介绍了光学仪器参数化设计软件系统（ＯＩＰｓ）的结构、功能特点，并以一实例加以说明。

CAD new technology-parametric design is stated in this paper.Starting with advanced CAD softwares soled in the world, several basic methods for parametric modeling and some new technologies such as feature-based modeling , constraint-based modeling,variational geometry and inference sketching are described.This paper introduces optical instument parametric design system(OIPS),including its architecture,functions and features. The procedureof designing a part is illustrated for stating parametric design benefit.
