Creating the surfaces by revolution

Rotation of the profile will be carried out in two rotations of 180 degrees each.

• From the Copy window, select Lines and Rotation. Enter an angle of 180 degrees. The axis of rotation is that defined by the line that goes from point (0, 0) to point (200, 0). Enter these two points as the First point and Second point (Two dimensions must be unchecked). From the Do extrude menu, select Surfaces.Be sure to enter 2 in Multiple copies. and select all lines and press ESC when the selection is finished.
• Rotate the view from the mouse menu Rotate->Trackball and choose Render->Flat to visualize a more realistic version of the model.

• Return to the normal visualization with Render->Normal. This option is more comfortable to work with. To return to the side view (elevation), choose in the mouse menu Rotate->Plane XY (Original).
