摘要
如何正确快速判断形体上线面的投影关系,是在阅读工程图过程中首先需要解决的问题.通过实例介绍了在读图过程中正确判断投影关系的几种有效方法,如读图时从一线框切入,区分相邻面的方位,判断视图中斜线投影的方法等.
It is first important to judge projection relation of lines and planes correctly and quickly while reading engineering drawings. By analyzing examples, this paper introduces methods to judge projection relation correctly such as starting with a wire-frame, distinguishing azimuth of adjacent planes and methods to judge oblique line projection.
