The Width property returns or specifies the width, in points, of a shape's outline. Assigning a value to this property automatically adds an outline to the shape if one does not already exist.
Examples:
The following VBA example creates an ellipse with an outline that is 0.1" in width.
Sub Test()
Dim s As Shape
Set s = ActiveLayer.CreateEllipse2(4, 4, 2)
s.Outline.Width = 0.1
End Sub
