CAD(Computer Aided Design)——计算机辅助设计是美国MIT的I.E.Sutherland于1962年首次提出的概念,自CAD技术问世三十年来,它随着计算机技术的不断提高,发展,迅速成为计算机应用的一个最普及的领域。它作为电子信息技术的一个重要组成部分,是高新技术改造传统产业,增强企业竞争能力,加快国民经济发展的一项关键技术。CAD技术是提高产品和工程设计的技术水平,降低消耗、缩短科研和新产品开发周期,大幅度提高劳动生产率,实现智能劳动自动化的重要手段。并已成为衡量一个国家、一个行业,一个企业科学技术水平的重要标志。一、CAD技术的发展CAD技术是以计算机为核心的信息技术,当这门技术发明后,欧美工业化国家首先相
CAD (Computer Aided Design) - Computer Aided Design (IAD) was first proposed by IESutherland of MIT in the United States in 1962. Since the advent of CAD technology in the past 30 years, it has rapidly become a computer application with the development of computer technology The most popular area. As an important part of electronic information technology, IT is a key technology of high and new technology reforming traditional industries, enhancing the competitiveness of enterprises and accelerating the development of the national economy. CAD technology is an important means to improve the technical level of products and engineering design, reduce consumption, shorten the research and development cycle of new products, greatly increase labor productivity and realize intelligent labor automation. And has become an important indicator of the scientific and technological level of a country, an industry and an enterprise. First, the development of CAD technology CAD technology is a computer-based information technology, when invented this technology, the first phase of European and American industrialized countries
