Extrusion
Extrusions are created with a specified thickness along a userspecified axis or along the patch’s
normal. Now, we will give the patch some thickness by extruding it along its normal to a picked
point.
1) Turn on the pickability of point clouds in the Set Selectable dialog (Selection | Set
