圆弧投影法是一种非线性变化,它具有不同于平行投影的基本性质。本文介绍应用圆弧投影法的特点和不变性质来解决正投影中的相交问题和工程上的某些交线作图的基本方法。通过实例说明了圆弧投影法在解决某些相交问题时的优越性。
Arc projection method is a non-linear change, it has a different from the basic properties of parallel projection. In this paper, the basic methods of applying the arc projection method to the characteristics and invariant properties to solve the intersection problem in orthographic projection and some of the intersections of engineering drawings are introduced. An example is given to illustrate the superiority of arc projection in solving some problems of intersection.
