CAD(计算机辅助设计)是随着计算机及其外围设备、计算机软件的迅速发展而形成的一门新兴技术,是电子信息技术与产业工程技术的结晶。自60年代第一代CAD商品化软件问世以来,CAD技术目前已广泛地应用于机械、电子、航空、航天、汽车、船舶、轻工、纺织、建筑及工程建设等各个产业领域,成为提高产品与工程技术水平、降低消耗、缩短产品开发周期、大幅提高劳动生产率和产品质量的重要手段。CAD技术及其应用程度已成为衡量一个国家科技现代化和现代制造业水平的重要标志。
CAD (Computer Aided Design) is an emerging technology formed with the rapid development of computers and their peripheral equipment and computer software. It is the crystallization of electronic information technology and industrial engineering technology. Since the advent of the first generation of commercial CAD software in the 1960s, CAD technology has been widely used in various industries such as machinery, electronics, aerospace, aerospace, automotive, marine, light industry, textile, construction, and engineering construction. With the level of engineering technology, reduce consumption, shorten the product development cycle, significantly increase labor productivity and product quality an important means. CAD technology and its degree of application have become an important indicator of a nation’s scientific and technological modernization and the level of modern manufacturing.
