Sub Example_Direction()

	' Create the Circle object in model space
	Set circleObj = ThisDrawing.ModelSpace.AddCircle(centerPoint, radius)
	
	' Change the thickness of the circle
	circleObj.Thickness = 3

	' Change the direction of the viewport so that you can
	' view the change made to the thickness. Once you change
	' the direction, you must reset the active viewport.
