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
