Sub Example_LeaderLength()
	' This example creates a diametric dimension
	' and returns the LeaderLength for that dimension.

	Dim dimObj As AcadDimDiametric
	Dim chordPoint(0 To 2) As Double
	Dim farChordPoint(0 To 2) As Double
	Dim leaderLength As Double

	' Define the dimension
	chordPoint(0) = 5#: chordPoint(1) = 3#: chordPoint(2) = 0#
	farChordPoint(0) = 5#: farChordPoint(1) = 5#: farChordPoint(2) = 0#
	leaderLength = 1#

	' Create the diametric dimension in model space
	Set dimObj = ThisDrawing.ModelSpace.AddDimDiametric(chordPoint, farChordPoint, leaderLength)
