AutoCAD Civil 3D

[#1]

I am trying to generate a floodway map for 20 miles of stream data.  I modeled everything in RAS and imported it into the River Analysis program.  Then, I saved the file and hit "Compute Analysis".  It gets about 85% complete and won't go any farther.  The green bar is still on the screen and in the bottom left corner of the screen, it still says "working", but I left it over night last night and it still didn't finish computing.  It does say "Initial Data Check . . . Finished", but when I hit cancel, it says "Cannot generate HEC-RAS data file".  Is my file too big?  Am I forgetting a step?  I can't figure out what's going on with it.  Any help would be greatly appreciated!

Thanks!

Without knowing what is in your HEC-RAS model, you might find it easier to import the HEC-RAS model and then import the results for mapping purposes only.

If the model sticks and does not complete the computation, it could be a number of possible items, including having an unsupported HEC-RAS item, to a permission issue.

Please forward a copy of your HEC-RAS model and the the River Analysis drawing for further analysis to labs.civil3d.river@autodesk.com

One of the first things to check is Permissions.  Matt suggested this and it remedied a situation for me.

Right-Click on the program icon  >> Properties>>Security and check Permissions are set for you.

Any update on whether the Package will be extended into 2013?  It is interesting software and would be helpful to finish working out the bugs.

Unfortunately I have not heard anything.

I work closely with our Hydraulic Modeling Group and I can say we are all looking forward to see how this plug-in progresses! As it stands, there are definitely some bugs in it. My Civil 3D 2012 did some really funny things after installing it but we are excited and eagerly awaiting to see where it goes...

Thanks for all of you hard work!!

We haven't had much opportunity to use this but definitely can see the need for it when we get another project that requires HEC-RAS.

I hope the development of this continues as well.

We have a HEC-RAS Model which contained 5 different scenarios for bridge replacement. Various spans and lengths. Am I understanding correctly that I must divide this into five different drawings within RAE when importing? I'd like to toggle through the various scenarios within RAE similar to HEC-RAS. Thank you Ron

I do wish the extension would be made to work with 2013. Right now, I'm having to support one AutoCAD 2010 license for a user so she can continue to work with the old BOSS RiverCAD. The rest of the company is on 2013. She's finding she cannot copy-paste information from 2013 into 2010. She does like RiverCAD and I hope (for my sanity) that Autodesk will incorporate River Analysis into a future release or at least make the extension permanent.

Civil 3D is not backwards compatible at all. I would imagine Map 3D is similar in nature. With Civil 3D you cannot copy and paste back one release even if it’s w/in the 3 year format without serious risk of corruption your drawing beyond repair. If you have to work in River Analysis then you have to keep those projects in ®2012. You can save a copy of them up to ® 2013 upon completion, but you cannot go back. (Although I do warn that I’ve converted VB Surface Models to .net Surface models and lost all of my break lines….

If you are on subscription you can run both ® 2013 and ® 2012 on her Machine with one license. Subscribers are allowed to run up to 3 releases back as long as they are on subscription. (Including Network Lic. as it’s built into the lic. file)
