Advanced Expansion

The advanced expansion check brings up two number boxes that control what happens when the Advanced Expand button is selected.  The first number is the number of rings around the current selection that advanced expansion selects.  The second number controls the maximum angle which the expansion will flow over.  This option allows you to select planar faces (angle < 1) or faces in a homogeneous region.  The left image below is a face selected.  The right image shows advanced expansion using the default settings.
