轴测图类型的选择方法探讨

Selective Methods of Axonometric Drawings

从轴测图类型选择的３ 条原则入手， 说明了利用轴测投影方向的水平投影、正面投影和 Ｏ Ｘ 轴的夹角ε１ 、ε２ 选择轴测图类型尚存不足， 阐述了解决思路， 基于轴测图的形成及正等测、正二测的ε１ 、ε２ 理论， 推导出了３ 种轴测图特定的轴测投影方向， 此结论弥补了ε１ 、ε２ 在轴测图类型选择方面的不足， 完善、丰富了轴测图类型选择理论．

Through the three principles of selection axonometric drawings,the author illustrates the deficiency of selection axonometric drawings,of which makes use of the angle ε 1 formed by the ox axle and level projection of the direction to axonometric drawing projection and the angle ε 2 by the facade projection.It has expounded how to deal with these problems.Based on the forming of axonometric drawings and ε 1、ε 2 principles of isometric drawing and Dimetric drawing,the author not only finds three kinds of projection direction to axonometric drawings but also induces and compares them with each other.This conclusion makes up the deficiency of ε 1、ε 2 in the selection of axonometric drawings and enriches and perfects the selection principles of axonometric drawings.
