Extrude   

		The Extrude tool can be used to add height to nearly any 2D shape.  This tool is useful when the shape you need to create is not a simple shape found on the Modeling toolbar.  To use the Extrude tool, click the icon and select whatever objects you want to Extrude.  Next you will need to enter the height of the Extrusion.  To the right you can see the variety of 2D shapes that can be Extruded.
