Sample Visual Basic Procedure
-----------------------------

   Sub DrawWave()

      On Error Resume Next

      ' Dimension the variables that hold the height and width of
      ' the presentation.
      Dim lh As Long, lw As Long

      ' Get the slide height and width.
      lh = ActivePresentation.PageSetup.SlideHeight
      lw = ActivePresentation.PageSetup.SlideWidth

      ' Clear the error object and get the current slide number.
      Dim lSlideNum As Long
      Err.Clear
      lSlideNum = ActiveWindow.Selection.SlideRange.SlideNumber
      If Err.Number <> 0 Then

         ' Display error message.
         MsgBox Err.Description, vbExclamation

         ' Stop the macro.
         End
      End If

      ' Draw a line down the middle of the screen.
      With ActivePresentation.Slides(lSlideNum).Shapes
         .AddLine 0, lh \ 2, lw, lh \ 2
      End With

      ' Create the first point of the free form shape.
      Dim oShape As FreeformBuilder
      With ActivePresentation.Slides(lSlideNum).Shapes
         ' Places the free form tool at its initial point.
         Set oShape = .BuildFreeform(msoEditingAuto, 0, lh \ 2)
      End With

      ' Peak point.
      oShape.AddNodes msoSegmentCurve, msoEditingAuto, lw \ 4, 0

      ' Middle point.
      oShape.AddNodes msoSegmentCurve, msoEditingAuto, lw \ 2, lh \ 2

      ' Valley point.
      oShape.AddNodes msoSegmentCurve, msoEditingAuto, 3 * (lw \ 4), lh

      ' Ending point.
      oShape.AddNodes msoSegmentCurve, msoEditingAuto, lw, lh \ 2

      ' Convert all the points created into a shape. If you do not call
      ' ConvertToShape the free form object won't appear on your slide.
      oShape.ConvertToShape

   End Sub
