    ' Read and display the original value
    originalValue = ACADPref.PolarTrackingVector
    MsgBox "The PolarTrackingVector preference is set to: " & originalValue

    ' Modify the PolarTrackingVector preference by toggling the value
    ACADPref.PolarTrackingVector = Not (originalValue)

    MsgBox "The PolarTrackingVector preference has been set to: " & newValue

    ' Reset the preference back to its original value
    '
    ' * Note: Comment out this last section to leave the change to
