REVOLUTION SURFACE
This function allows the user to create a surface by rotating a selected line as a section (generatrix) about a vector (axis of revolution).
Select the endpoints of the axis in the INPUT COORDINATE dialog window. A vector will be displayed after the second point is selected.
Select a line as the section (generatrix).
Enter the start and end angles in the dialog window. See Figure 5.2.2. Select OK, and the surface will be generated after the window is closed.
