Application of projection characteristics in learning engineering drawing

Zhanwen Wu

Abstract

From the projection characteristics of the point line plane, we can conclude: Their projection has at least a similar or solid form (long) projection. It's easy to imagine how do the lines; planes and solids exist in fact. This text related how to make the similar or solid projection according to the projection characteristics, and how to educate the space to think the elephant ability.
