摘　　要：针对汽车覆盖件的特点和模具CAD／CAM的要求，结合当前产品造型的发展现状和趋势，对曲面造型系统进行了研究。在微机上以Windows3．1为平台，开发了一个曲面造型系统。该系统由四大模块组成，即用户界面模块、线框造型模块、曲面造型模块和数据管理模块。阐述了系统的整体结构、数据结构、数学方法以及主要算法。For the special factures of car shut metal parts and requirements of CAD/CAM of die, together with the state of art and future development of current product styling,curved surface forming system is studied. With window 3. 1 in microcomputer as platform,a curved surface forming system is developed. This system consists of four large modules,i. e,userls interface , line frame forming, curved surface forndng, and data mampement modules. System's total structure, data structure,math method and main algorithm are all given in this article.
