    Dim currSegmentPerPolyline As Integer
    Dim newSegmentPerPolyline As Integer
    
    ' Retrieve the current SegmentPerPolyline value
    currSegmentPerPolyline = ThisDrawing.preferences.SegmentPerPolyline
    MsgBox "The current value for SegmentPerPolyline is " & currSegmentPerPolyline, vbInformation, "SegmentPerPolyline Example"
    
    ' Change the value for SegmentPerPolyline
    newSegmentPerPolyline = 2001
    ThisDrawing.preferences.SegmentPerPolyline = newSegmentPerPolyline
    MsgBox "The new value for SegmentPerPolyline is " & newSegmentPerPolyline, vbInformation, "SegmentPerPolyline Example"
    
    ' Reset SegmentPerPolyline to its original value
