Extrude

Another very useful modeling tool is Extrude. To understand how it works, imagine the floor of a house. You select the floor and, when you extrude it, you move it up as if it were a duplicate to create a ceiling, but then Blender will generate the walls to join the floor and ceiling (see Figure 6.11). You can use Extrude for vertices, edges, and faces.
