Yes, River Analysis can read in the HEC-RAS project file and then can load the results for floodplain mapping.
OK I think I have found that option now for writing out the floodplain lines. Ta.
Any News on a version for 2013?
Yes, River Analysis works with latest the AutoCAD Civil 3D 2012 service pack.
Did you encounter this error when opening a prior drawing or just on launch.
I would suggest uninstalling and reinstalling River Analysis, but it launches, and imports without issue on SP2.1.
I did that before my first message, and just reinstalled again this morning and still get the "unexpected error quitting" message. I am also getting this message when closing the program.
I assume you had it working prior to SP2.1? The first download of extension expired in December, and the latest version extended that original date. I assume you have the latest download.
For installation, check prior posts to verify that the files are copied correctly and your River Analysis icon has the necessary Administrative privileges.
As for the last error, its a bit difficult to tell what didn't close prior to AutoCAD Civil 3D closing. Its a benign error.
I just right-clicked on the imperial icon now and ran as administrator as you suggested and it launched without that error.
Yes I did have it running before.
Thanks for the help Matt.
