Sub Example_Select()
	' This example adds members to a selection set, first by crossing and
	' then by filtering for circles.

	' Create the selection set

	corner2(0) = -3.3: corner2(1) = -3.6: corner2(2) = 0
	ssetObj.Select mode, corner1, corner2

	' Add all the Circles to the selection set that lie within the crossing of (28,17,0) and
