There are videos on the download page and the help file covers it all.
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!?
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.
