Sure hope someone can help. I am trying to export the flood boundary data from HEC RAS and import it into Civil 3D 2011. The file I export from HEC RAS 4.1.0 using the GIS Export tool looks good. I am almost certain that up to this point there is no problem with the process or the exported file. However, when I import it into Civil 3D, the alignment looks good and is a true alignment, but the profiles (Q2, Q10, etc.) are listed under the alignment but do not have any data associated with them. Any suggestions?
