Revolve

		The Revolve tool will take a 2D drawing and rotate it around a central axis.  To use this tool, you need to have some kind of drawing that can be rotated around.  To use the Revolve command, first select which items you want to rotate in order to create the new object.  These items will be the "cross-section" of the object after the Revolve command is done.  Once everything is selected, you will need to select the first and second points of the axis of revolution.  By selecting these two points, you are creating the line around which AutoCAD will rotate the first objects you chose to revolve.  It is not necessary to have the axis of revolution drawn, but it has been included here to show how this tool works.
