Culvert/Bridge Modelling with Hec GeoRAS

Culvert/Bridge Modelling with Hec GeoRAS

Culvert/Bridge Modelling with Hec GeoRAS

Could someone please explain the procedure to export bridge/culvert data from ArcMap to Hec-RAS using the Hec GeoRAS extension? I tried following the GEO-RAS manual,creating all the "ras layers" etc. All my channel cross-sections showup after using the "import Geometry Data" option in Hec Ras; However, I must be doing something wrong with the culverts, because when I go to the Bridge Culvert Editor, there are no upstream and/or downstream cross-sections showing up in the "data plot" window, even after specifying the "new culvert station" and pressing "apply", Also, the distance between Xs is shown as "0 feet for some reason, even though it clearly is not the case considering the bounding Xs stations. Could this be linked to how the cross-sections are positioned?
