Discussions about the One Time Rotation of a Body of Revolution to the Designated Position

In this article, the one time rotation of a body of revolution to the designated position under any conditions is studied, especially when the rotating front and rear of a body of revolution are on different planes, in which case, descriptive geometry graphic solution is employed to solve the rotation axis and rotation angle. Compared with other methods, this method is simpler and more visible. The solution of the problem will greatly contribute to the simplification of production processes, thus lowering product costs and improving economic benefits.
