图和文字、数字一样,是人类用来表达、交流思想和分析事物的基本工具之一。工程技术上则用“图样”来表达设计思想、进行技术交流和指导生产。所以,图样素有工程界语言之称。工程技术上除用图样指导生产外,还用图来解决科学技术上的空间定位、度量和数学计算等问题,描述、分析各种客观现象和实验数据,借以探索事物的规律性。工程图学所研究的就是这类与工程技术有关的工程图。自法国数学家蒙日(Monge)创建《画法几何》,奠定了工程制图的理论基础以来,经历了两个多世纪。在这两百多年中,图学理论进展缓慢,技术上仍以手工操作为主,与飞
Figure and text, like numbers, is one of the basic tools used by human beings to express, exchange ideas and analyze things. Engineering is the use of “design” to express the design ideas, technical exchanges and guide the production. Therefore, there are drawings of engineering language known. In addition to using engineering drawings to guide the production, but also to solve the scientific and technological map of the spatial positioning, measurement and mathematical calculations and other issues, describe and analyze various objective phenomena and experimental data, in order to explore the regularity of things. Engineering Graphics Institute is the study of such engineering and engineering drawings. Since the French mathematician Monge founded the “painting geometry” and laid the theoretical basis of engineering drawing, it has gone through more than two centuries. In these two hundred years, the slow progress in the theory of graphics, the technology is still mainly manual operation, and fly
