Sub Example_StandardScale()
	' This example will access the active layout for the current drawing
	' and list the standard scale for that Layout.
	' It then changes the standard scale for the layout, and finally
	' resets the scale back to its original value.

	Dim Layout As ACADLayout
	Dim currScale As Integer

	' Get the activeLayout
	Set Layout = ThisDrawing.ActiveLayout

	' Find the current standard scale
	currScale = Layout.StandardScale
	MsgBox "The current standard scale is : " & Layout.StandardScale

	' Change the standard scale to 100:1
	Layout.StandardScale = ac100_1
	MsgBox "The new standard scale is : " & Layout.StandardScale

	' Reset the original standard scale
	Layout.StandardScale = currScale
	MsgBox "The new standard scale is : " & Layout.StandardScale
