摘　　要：探讨了开源几何内核库Open CASCADE的特点,着重介绍了基础类、造型数据类、造型算法类、可视化类等主要功能模块,给出了几何模型构建、几何运算、可视化操作等功能开发的基本过程,研究了基于Open CASCADE平台的CAD系统开发的一般方法。使用该方法开发了一款小型三维CAD系统,能够实现几何建模、几何运算和数据转换等功能。The characteristics of an open source geometry kernel library named Open CASADE were discussed. The main function modules like Foundation Classes,Modeling Data,Modeling Algorithms,Visualization were particularly introduced. The basic programming process of geometric modeling,geometric computing,visualization operation were presented to figure out a general method of CAD software development based on Open CASCADE platform. Based on this method,a small 3D CAD software which enables geometric modeling,geometric computing,and data conversion was developed.
