Selective Methods of Axonometric Drawings

Abstract：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.
