摘　　要：同轴的圆柱与圆锥之间所形成的阴影是建筑形体中较为常见的。在确定阴影的范围时,常用近似方法求得。针对柱锥落影中影线的准确确定,讨论了其作图的新方法,解决了完整影线的准确作图问题。The shadow formed by cylinder and circular cone at the same axis is often seen in architectural shapes. When the range of the shape is determined, the method of approximation is often adopted. In dealing with the accurate determination of the shadow of the line of cylinder and circular cone shade, this article focuses on the new methods of drafting shadows, and therefore solves the problem of accurately drafting of the shadow of a complete line.
