中国古代工程制图的形成和发展,历经了数千年的岁月,有着自身独立的学术系统和图学理论系统.自远古以来,中国古代的图学家们成功地运用数学的方法,指导工程图样的绘制,为中国古代科学技术的发展起到十分重要的作用.本文以此为题论述了中国古代工程制图理论中的数学基础,第一,比例在工程制图中的应用;第二,投影方法的应用及其总结;第三,对基本视图的认识与运用.“,”Based on diagrams and calculation,modern engineering drawing methods are the basic means of expression for scientific and technological thought.The formation and development of these methods have taken place over thousands of years.Science remote antiquity engineers and scientists have been able to successfully produce accurate drawings based on mathematical methods.It is important to study a history of engineering drawing This paper will discuss the mathematical basis for engineering drawing in ancient China.First the use of scale in engineering drawings will be examined ,Next,projection methods,such as parallel projection and central projection,will be reviewed in depth.Finally,the knowledge use of basic views will be discussed.
