用正等测图配绘体视图对的简便方法

工程技术人员表达自己的设计思想，通常使用正投影图、轴测图、透视图等方法。这种用平面图形表达空间物体的方法，均需按各自的投影规律去想象，因此立体效果较差。体视投影利用了人眼观察物体的原理，立体感很强。它可以形象地表现空间物体、表达设计意图，便于观察修改，也可作为教学的辅助工具。本文介绍了一种用轴测图配绘体视图对的方法，原理简单，画法方便，一般工程技术人员均可使用。

A Simple and Convenient Method for Drawing the Stereo Pair by Trimetric Drawing

In order to express idea of the designers,the designers usually use the methods such as orthogonal projection, axonometric projection and perspective projection etc.These methods that use the plane views to show the space bodies are accordance with its own projection rules respectively. Therefore the stereo effects are worse,but the stereo effects of the stereo projection are very strong. since it uses the principle of visual observation on the stereo projection,it can express the space objects imaginably, and express the design ideas easier,So it is easier to check and modify. and it can be used as an auxiliary tool in teaching.This paper introduces the method to draw the stereo pair by axonometric projection,the principle and technique are simple and convenient,So it can be adopted by the ordinary technicians.
