Extending a line by creating a segment (Aeronautical Solution)

Lines can be extended by clicking a location or drawing a new segment to extend a line past an end point. The Dynamic Extend tool allows you to extend a selected line by clicking on or near the endpoint to extend from and adding one or more vertices to represent the new segment that will be added to the line. The line can be extended from either end without the need to flip the sketch direction.
