Creating bypasses

Create Bypass is one of the options for the Line Bypass tool. On some Enroute charts, areas become congested with text, features, and additional information. In these cases, line bypass symbology can be used on ATSRoute features to eliminate the need for note text informing a pilot to not report at a designated point.
