| Abstract: | 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. |
