轴中心投射——一种新的投射方法

The Axis-Central Projection——A New Projecting Method

本文提出一种新的投射方法和非点中心投射的概念,对文中建立的轴中心投射法进行了探讨,总结出一系列投影规律。本方法的提出可使一些图解问题得以简化,为工程上解决与螺旋曲面有关的图示图解问题带来方便。

In this paper, the new project method and the concept of non-central projection are presented. The axis-central projection method put forward in this paper is studied. A series of project rules are gained. The method is an efficient and convenient way on viewing or solving the problem associated with helicoid in engineering.
