Reverse Alignment Direction: After selection of a polyline, you can use the "Reverse" icon to reverse the
direction of the alignment, ensuring that it increments the stationing in the desired direction. This feature is found
throughout the software where horizontal alignments are selected from the screen. In the case of File-based or
Point-based alignments, the direction is defined by the file or point order itself. This option is available within Stake
Offset, Point Projection, Station Store, Store Sections, Stake Slope and Stake Road.
