I have been trying to import/export information to create a flood map using hec ras. I succesfully (not without some pain), imported the geometric data into HEC RAS and did my analysis. I create the .sdf and try to import it to Civil 3D, but, while it appears to have imported succesfully, it does not show the water lines.
As a matter of fact, CIVIL3D indicates at some point that the minimim and maximum elevations are both 0.00m.
I checked the .sdf file, which I attach, and it looks fine to me. It has the information of the water level as it should.
I think I´ve watched every video avilable and i can´t seem to find the answer.
Thanks a lot for your help!!!
i have faced some issues with the SDF import in the past and decided to to go the "CREATE PROFILE FROM FILE" route. after i run steady/unsteady state, from the tables window, i save the STA and WSE as a text file, that i can import to automatically create the water surface profile in my stream centerline (HEC-RAS reach) profile view. from there on, i can create the floodplain by stepped offset feature lines, or a corridor.
sorry, not the answer you are looking for, cannot help much with the SDF.
