Outline Polylines are straight lines connected by a series of marked fit points. Polylines differ from Outline Lines in that they are a series of straight-line segments connected by points. Polyline mode is a shorthand for drawing a series of Outline Lines that start where the last ended. The ends of a Polyline can be filleted. At any time in this mode, an existing Outline point can be clicked and dragged to adjust its photo position.
