Culvert modeling information.

Question

When I uploaded my information from AutoCAD Civil 3D, I needed to switch my coordinates. This is having a great effect on my culverts, they show the incorrect stationing for the upstream and downstream x-sections.

Per autodesk.com:
To Reverse the flow direction in Hec Ras, go to the Geometric Data editor> GIS Tools> Search Invert Lines Table > and Flip Coord. Order.
