摘要
提出利用特殊位置辅助面截交线投影的特点(45°投影面垂直面、底角45°圆锥面及其它特殊位置垂直面)求解画法几何中的截交线与相贯线(平面立体截交线、圆柱与圆锥的截交线;圆柱与圆柱,圆柱与圆锥的相贯线)以及直线的落影、回转曲面立面阴影的作图方法。
Using the projection feature of intersection of special auxiliary plane (the vertical plane of 45o, 45o bottom angle conical surface and other special position vertical plane), this paper put up the constructive method of the line of section of a plane with a planar solid, (one of a plane with cylinder cone;the tridimensional transversal of the line of intersection between two cylinders and one between a cylinder and a cone) and the shadow of line and, the vertical plane shadow of surface of revolution in descriptive geometry.
