    Set Layouts = ThisDrawing.Layouts
    
    msg = vbCrLf   ' Start with a space
    
    ' Get the paper units information of every layout in this drawing
    For Each Layout In Layouts
        ' Using inches or millimeters?
        Measurement = IIf(Layout.PaperUnits = acInches, " inches", " millimeters")
