There is a new technology preview on Autodesk Labs.
http://labs.autodesk.com/utilities/civil3d_river/
Project River Analysis Extension for AutoCAD® Civil 3D® 2012 software and AutoCAD® Map 3D® 2012 is a sophisticated river modeling software package supports HEC-RAS within the AutoCAD Civil 3D 2012 and AutoCAD Map 3D 2012 environment. This technology preview of River Analysis makes it easier than ever before to compute water surface profiles for modeling rivers, bridges, culverts, spillways, levees, floodplain and floodway delineations, stream diversions, channel improvements, and split flows.
Hi all,
Thanks Bill for your suggest, but in my Start-All menu I haven't any icon for RAE.
I rebuilt it manually with this from the Civil 3D one with this destination:
"C:\Program Files\Autodesk\AutoCAD Civil 3D 2012\acad.exe" /ld "C:\Program Files\Autodesk\AutoCAD Civil 3D 2012\AecBase.dbx" /p "<<C3D_Italy>>"
And especially from:
"C:\Program Files\Autodesk\Project River Analysis 2012"
I found also the Icon, in the RAE folder.
The link for myGIS&INfrastructure Blog is:
You can read it using Google Translate.

Many thanks!

Finally recieved some HEC/RAS info to try out in the program!!! All seemed to be working well until I tried to "Compute Analysis"
I was able to Import the HEC/RAS project. It seemed to draw all the components (reach, profiles, cross sections) All the section had data that matched the rersults in HEC/RAS etc... but when I clicked on "Compute Analysis" it gives the error message:
Run-time error '429':
Active X Component can't create object
Any help would be appreciated.
Thanks
Edit: This is being done with Civil 3d 2012 (32bit) and Windows XP if it matters.
Thanks for the reply. I was going over the install and remembered that one of the files failed to register. So that could also be the issue.
I tried the Retry multiple times but finally hit the ignore. I wonder if there is a way to manually register this file? If not it looks like a re-install might be coming...
What operating system did you install on?
Did you turn OFF User Account Control to install?
This was on Windows XP so the "User Account Control" isn't applicable. I do have full admin privileges on the account.
I played around with this last week and hit a brick wall with an 'Error Loading Geometry File' (from HEC Ras) when I ran the computation.
The app really needs to work with C3D objects (alg, profiles and sections).
The app did not like 2d or 3d polylines for a 2 stage weir I had to model.
Overalll I loved the product and the workflow.

I have the same issue. I was able to import XS from Hac Ras, however when I run it, I see the same error message, can somebody tell me what to do? Thanks!
(my system info
Intel Xron Processor 3.07 GHZ
Winow 7 64-bit
Nvidia Quadro 2000)
When I start the program, I will see this mesage
Hi;
i want to know is it designed to perform two-dimensional hydraulic calculations for a full network of natural and constructed channels or its one-dimensional hydraulic calculations software similar to HEC-RAS!?

Mehrdad -
River Analysis is HEC-RAS within Civil 3D and/or Map 3D.
It would be nice if the RAE could be linked to alignments with the ability to set the centerline as a certain station from which the left to right section stationing could be derived by the computer and not have to be input.
I.E. Using a defined alignment with centerline being the 0+00 or 1+00 for all sections then station label, length between stations, station of all sections could be defined by just clicking on the section lines that I plot along my alignment. This would give my section plotting some relative reference to centerline.
Currently I have to define an alignment, label all of the sections and the offset at the end right of the section (downstream left), then reenter all of that info as my starting section. It would seem the computer could do all of that for me if it had a definited alignment.
I've seen reference to avoiding negative stations in cross sections, which I have done in the past, but it would be prefered from my POV to have neg be downstream left and positive downstream right of CL.

I second this.
As it stands right now, the Center line of the reach almost appear to be random. I am selecting it to automatically cut the sections, why can't this be stored in the reach. An Alignment would be even better.
The HEC-RAS text file supports a centerline.
The technology preview is conducted so that the River Analysis team can get feedback on the technology. Right now they are getting plenty of feedback from the AutoCAD Civil 3D 2012 user base. If they decide they would like to expand the audience to collect additional feedback, they may conduct a 2013-based technology preview.
Is it possible to read in a HEC RAS analysis that has already been calculated in HEC RAS, and have the results displayed using the RAC tools in Civil3D?
I can't seem to see a way of doing that. Thanks.
