The Outline property returns the outline (or Outline object) applied to a text range.
Examples:
The following VBA example changes the width of the last word of the paragraph to 2 inches.
Sub Test()
Dim d As Document
Dim s As Shape
Dim t As Text
Set d = CreateDocument
Set s = d.ActiveLayer.CreateParagraphText(2, 2, 4, 4, "This is an example.")
Set t = s.Text
t.Story.Words.Last.Outline.Width = 2
End Sub
