Polylines
Introduction
This section covers Polylines, which function like Areas but they do not have to be enclosed spaces. You can create a polyline line by line.

Polyline Properties
Polylines have a set of properties that can be used control their appearance:
Name: The Name field allows you to rename the polyline after creating it. There is no limit on length, and it is sensible to use a meaningful name.
Hidden: This option physically hides the perimeter on the map and it will not be used for tracing. To amend this setting on a hidden area, you will need to select it from the object properties list.
Font Size: This controls the size of the text that is displayed when labels are shown. The drop-down allows for a font size between 10 and 20 points, with 20 being the default size. If there are a lot of areas that are closely packed together, showing area labels will result in a cluttered display. In this case it may be better to switch off all labels except for the prominent ones.
Display Label: If deselected, the label for the area will not be displayed.
Colour: This option displays a colour picker that will allow you to choose the display colour of the area. By default it is red.
Stroke Size: This controls the size of the plotted outline of the area.
Obstruction: When enabled, the polyline will be used in the calculation for determining what a radar can see https://navtechradar.atlassian.net/wiki/spaces/PROD/pages/3999825921.

You can also left-click and drag on one of the translucent white dots to add an extra white node:
To drag a perimeter around the map, hover your mouse over the polyline until the curser changes from an open hand shape to a hand with a pointed finger, then hold down the Ctrl key and press the left mouse button to drag it around.
If you are unhappy with the editing, you can click Cancel and this will undo the last changes.
