Examples:
The following VBA example creates a line. An arrowhead is applied to the start position of the line, and the zoom of the active window is increased to 200%. The ReverseDirection method is applied, and the arrowhead that was initially applied to a specific end of the line now appears at the opposite end of the line.
Sub CurveReverse()
Dim s As Shape
Set s = ActiveLayer.CreateLineSegment(0, 0, 5, 5)
s.Outline.StartArrow = ArrowHeads(3)
ActiveWindow.ActiveView.Zoom = 200
s.Curve.ReverseDirection
End Sub
