    ' Retrieve the current ContourLinesPerSurface value
    currContourLinesPerSurface = ThisDrawing.preferences.ContourLinesPerSurface
    MsgBox "The current value for ContourLinesPerSurface is " & currContourLinesPerSurface, vbInformation, "ContourLinesPerSurface Example"
    
    ' Change the value for ContourLinesPerSurface
    newContourLinesPerSurface = 2001
    ThisDrawing.preferences.ContourLinesPerSurface = newContourLinesPerSurface
    MsgBox "The new value for ContourLinesPerSurface is " & newContourLinesPerSurface, vbInformation, "ContourLinesPerSurface Example"
    
    ' Reset ContourLinesPerSurface to its original value
    ThisDrawing.preferences.ContourLinesPerSurface = currContourLinesPerSurface
