Sub Example_Measurement()
	' This example creates an aligned dimension in model space
	' and returns the measurement of the dimension; in the case
	' of a linear dimension, this measurement will be its length

	Dim dimObj As AcadDimAligned
	Dim point1(0 To 2) As Double, point2(0 To 2) As Double
	Dim location(0 To 2) As Double
	Dim CurrentValue As String

	' Define the dimension
	point1(0) = 5: point1(1) = 5: point1(2) = 0
	point2(0) = 9: point2(1) = 5: point2(2) = 0
	location(0) = 5: location(1) = 7: location(2) = 0

	' Create an aligned dimension object in model space
	Set dimObj = ThisDrawing.ModelSpace.AddDimAligned(point1, point2, location)
	ThisDrawing.Application.ZoomAll

	' Read and display current measurement
	MsgBox "The current measurement of the new dimension is: " & dimObj.Measurement
