摘要
提出仅用两面投影图求交叉二直线间最短水平连线和最短给定坡度连线的方法,这种方法优于惯用的换面法。
The paper presents new graphic methods to find the shortest horizontal line and the shortest line at specified grade connecting two skew lines by only using the two principal views. This method has the advantage over traditional graphic method of transformation of projective planes.
