Sub Example_LinetypeGeneration()
	' This example creates a polyline in model space and
	' queries and changes the linetype generation for
	' the polyline.

	' To see the effect of changing the linetype generation, set
	' the linetype of the polyline to something other than continuous,
	' ByBlock, or ByLayer.

	Dim plineObj As AcadPolyline
	Dim points(0 To 14) As Double

	' Define the 2D polyline points
	points(0) = 1: points(1) = 1: points(2) = 0
	points(3) = 1: points(4) = 2: points(5) = 0
	points(6) = 2: points(7) = 2: points(8) = 0
	points(9) = 3: points(10) = 2: points(11) = 0
	points(12) = 4: points(13) = 4: points(14) = 0
	
	' Create a lightweight Polyline object in model space
	Set plineObj = ThisDrawing.ModelSpace.AddPolyline(points)
	ZoomAll

	' Find the current linetype generation for the polyline
	MsgBox "The linetype generation for the polyline is: " & plineObj.LinetypeGeneration

	' Change the linetype generation
	plineObj.LinetypeGeneration = Not plineObj.LinetypeGeneration
	plineObj.Update
	MsgBox "The linetype generation for the polyline is now: " & plineObj.LinetypeGeneration
