I downloaded the latest Hec-Ras version (5.0.3). I need to reverse the station data at each cross-section for a reach.
Usually in Geometry Editor>Tools>Reverse XS Stationing and Cut lines I could do this. Now in the latest version the option is no longer there, but the manual still refers to it being under Tools on page 6-166.
Luis is heading in the right direction, but when I did the "Reverse Cut Lines" tool it didn't switch the stationing. The tool "GIS Tools > GIS Cut Lines > Reverse XS Stationing and Cut Line Data" does the job.
