What is a Polyline?
A polyline is a user-defined line, made up of at least two points. The most common
use for polylines is to indicate where nets are, or to indicate an area which should be
avoided. These lines are not convertible to a route and appear in addition to the chart
marks and lines.

How to Create a Polyline
Polylines are a combination of several straight lines. Each straight line is referred to
as a "Vertex".
1. Tap the location you want to start a polyline from. The pop up menu appears.
2. Select [New Polyline]. A point appears at the selected location.
3. Tap the location for the next point in the polyline. A line appears between the first
point and this point, making the first vertex of the polyline.
4. Repeat step 3 as necessary to complete the polyline.
5. Tap [Save] to save the new polyline.
The polyline is saved in the [Polylines] list, under the [List] menu.
