国内外CAD技术现状及其发展趋势

Current State and Prospects of CAD Technique in China and Abroad

介绍近年来国外一些工业发达国家和我国在CAD 技术领域中的开发应用研究现状,并由此指出:CAD/CAM 总的发展趋势是集成化、智能化及网络化.发展CAD 技术的重点是CAD 软件的发展.此外,从CAD/CAM 系统来看,以个人微型计算机为基础的系统以及可以联网成高功能系统的32位工作站是未来发展的趋势;从采用CAD/CAM 的企业规模来看,CAD 技术正在向中小型企业扩大.

This paper introduces the current state of development,application and researchin the field of CAD technique both in China and developed countries.The authors pointedout that the general tendency of CAD/CAM is integration,intelligence and network.Thekey of the progress of CAD technique is the development of CAD software,and as viewfrom CAD/CAM system,which based on personal microcomputer and network forming32-bit workstation of high performance is the future trend;the application of CAD tech-nique is now being spreaded to medium and small enterprises.
