摘要:
如何由两交叉直线段的基本投影,经过几次变换投影面,使其辅助投影成为等长而夹成定角的两直线段?这是图解方法中的一个基本问题,关键在于确定获得这一辅助投影的投射方向。本文就两交叉直线段为等长或不等长的两种情况,分别介绍确定这一投射方向的图解法,并作出相应的辅助投影。
Abstract:
How can the principal projections of two segments of skew lines be transformed by several steps of substitution of projection planes into auxiliary projections of equal lengths with a given included angle? This is a basic problem in graphical method. The essence of the problem is to define the direction of projection, from which the auxiliary projections as required above, will result. This paper presents a graphical method for defining the direction of projection for two segments of skew lines of either equal or unequal lengths respectively. The corresponding anxiliary projections are also shown.
