Hello everyone, I'm having a similar problem. I'm trying to export RAS data form GeoRAS for use in HEC RAS but arcMap keeps crashing. I'm using ArcMap 10.8.2 on Windows 11. Please I need help

Hello, again!!

it seems that the problem  was that the tin i was using had not the correct projection system.
everything is working fine now.
Thank you for the help anyway.

try unchecking everything but your cross sections and centerline in the RAS GIS export.... Minimize what its trying to bring in and see at what point it starts to mess up.

Other than that....Create a really basic geometry file in ras.  2 cross sections and just the a hand drawn centerline in the geometry editor.  Try exporting that and see if that comes in ok.  If it does then it narrows the issue down to your specific project file.  If it doesnt then something is probably wrong with georas.

If its your project file, try saving a new copy of the model and re-exporting the data.
If its georas, uninstall it and reinstall to see if that fixes it.
