    ' This example reads and modifies the preference value that controls
    ' whether symbol names may include extended character sets, or more
    ' than 31 characters.
    '
    ' When finished, this example resets the preference value back to
    ' its original value.
    
    Dim ACADPref As AcadDatabasePreferences
    Dim originalValue As Variant, newValue As Variant
    
    ' Get the user preferences object
    Set ACADPref = ThisDrawing.preferences
    
    ' Read and display the original value
    originalValue = ACADPref.LineWeightDisplay
    MsgBox "The LineweightDisplay preference is set to: " & originalValue

    ' Modify the LineweightDisplay preference by toggling the value
    ACADPref.LineWeightDisplay = Not (ACADPref.LineWeightDisplay)
    newValue = ACADPref.LineWeightDisplay
    MsgBox "The LineweightDisplay 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
