Sub Example_ADCInsertUnitsDefaultTarget()
    ' This example reads and modifies the ADCInsertUnitsDefaultTarget
    ' preference value.
    ' When finished, this example resets the preference value back to
    ' its original value.
    
    Dim ACADPref As AcadPreferencesUser
    Dim originalValue As Integer, newValue As Integer
    
    ' Get the user preferences object

    Set ACADPref = ThisDrawing.Application.preferences.User
    
    ' Read and display the original value
    originalValue = ACADPref.ADCInsertUnitsDefaultTarget
    MsgBox "The ADCInsertUnitsDefaultTarget preference is set to: " & originalValue

    ' Modify the ADCInsertUnitsDefaultTarget preference by toggling the value
    ACADPref.ADCInsertUnitsDefaultTarget = acInsertUnitsMillimeters

    MsgBox "The ADCInsertUnitsDefaultTarget preference has been set to: " & ACADPref.ADCInsertUnitsDefaultTarget

    ' Reset the preference back to its original value
