Extruding Polygons
	To extrude a polygon, first click Geometry Edit on the WorldEdit toolbar (for information about editing modes, see the Selection and Manipulation section). Place the cursor over the target polygon, so that it is selected. Press and hold E and drag with the right mouse button. The polygon is extruded along the axis of its normal, that is, perpendicular to its plane.
