在工程技术界,图纸是表达设计意图和指导生产施工的重要资料。随着电子计算机在现代工程设计、生产、试验中应用范围的迅速扩大,它也变成了工程技术人员绘图的得力工具。最近,三机部技术考察组访问了美国道格拉斯和洛克希德两家飞机公司,看到了计算机绘图的某些应用。虽然这些公司的业务领域有较大的特殊性,但是从计算机绘图的角度看,也反映了美国当前较先进的 In the engineering and technical community, drawings are important materials for expressing design intent and guiding production and construction. With the rapid expansion of the scope of application of electronic computers in modern engineering design, production, and testing, it has also become a powerful tool for engineers and technicians to draw. Recently, the three-machine technology inspection team visited two aircraft companies, Douglas and Lockheed in the United States, and saw some applications of computer graphics. Although the business areas of these companies are quite special, from the perspective of computer graphics, it also reflects the current advanced nature of the United States.
