Thank you for your reply

I am also having this issue right now. I am changing the size of my cross sections in RASMapper, saving everything, then exiting RASMapper. After opening up geometry editor, the cross sections have not changed at all. I reset HEC-RAS and still the cross sections are not updating. The only thing I can think of is either manually entering in all the values, or starting over with better cross section design initially in RASMapper.

I can’t figure out how to edit or delete this post. But I am an idiot and was checking the results for a previous run, and not the run with the culvert installed. Please ignore.

Did you ever find a solution to this? My model was working fine until I updated my weir/dam and now I am getting this error between my SA/2D connection when trying to compute an unsteady flow analysis.

I have. I re-exported data from Civil 3D to Hec-Ras and updated all the necessary parameters. I still get odd changes in WSE that don’t seem right. When I lower mannings, water should move through the channel quicker, thus a lower WSE. I don’t know. I was just hoping somebody else might have seen this happen as well.

Thanks though
