| 摘 要： | 对于一般二次曲面（即椭圆面、椭圆抛物面、双曲面等）形体的截交线、相贯线，如采用辅助平面法作图，步骤繁琐而且不够精确。为了解决这一问题，文中在工程图学范围内应用透射变换的方法，使一般二次曲面变换成圆，从而达到了简化作图的目的。

| Abstract: | For the intersecting lines between the general conicoids such as oval face,elliptic paraboloid and hyperboloid,the auxiliary plane mapping method is cumbersome and not precise.Here a perspective transformation,in the range of engineering plot,is applied to transform the conicoid to circle so as to simplify the plotting mapping. |
