当几何元素相对投影面处于特殊位置时,其投影能直接反映实形或有积聚性,此时度量问题比较简单;但当处于一般位置时,其投影不具有以上特点,度量问题就比较复杂.本文分几种情况分别讨论了利用换面法将一般位置直线或平面转换至对投影面的特殊位置,以简化图解度量问题.
噹幾何元素相對投影麵處于特殊位置時,其投影能直接反映實形或有積聚性,此時度量問題比較簡單;但噹處于一般位置時,其投影不具有以上特點,度量問題就比較複雜.本文分幾種情況分彆討論瞭利用換麵法將一般位置直線或平麵轉換至對投影麵的特殊位置,以簡化圖解度量問題.

When the geometry elements in a special position relative to the projection plane, its projection can directly reflect the real shape or accumulation, and the measurement is simple; But when in a general po-sition, its projection do not have the above characteristics, measurement problem is more complicated. This paper respectively discusses the changing surface method which is used in several conditions to transform general position straight line or plane to the special position of plane, in order to simplify the diagram to measurement problems.
