Editing Polygons

Polygons and rectangles are edited by modifying the visual points that represent their points or vertexes (waypoints). For polygons, waypoints can be added, deleted or moved to resize or reshape the polygon. For rectangles, waypoints cannot be added or deleted; they can only be dragged to resize the rectangle.

Waypoint markings indicate the following:

Marking	Indication
White Waypoint	Waypoint in a selected polygon.
Red Waypoint	Selected waypoint.
Green Waypoint	Waypoint that is not selected but that the cursor is pointing to.
