The Polygon property returns a Polygon object that represents the settings for a symmetrical polygon shape.
Examples:
The following VBA example converts all symmetrical polygon shapes on the active page to five-point star polygons.
Sub Test()
Dim s As Shape
For Each s In ActivePage.Shapes
If s.Type = cdrPolygonShape Then
s.Polygon.Sides = 5
s.Polygon.Type = cdrStar
End If
Next s
End Sub
