I'm trying to export my geometry of my river to HEC Ras using HEC Geo RAS in Arcgis 10.2.1. So I did the whole process in ArcMAP and I get an ''Failed to create intermediate ESRI XML file!Object reference not set to an instance of an object.'' More exactly, when the system information compiled, the exact error that I get is ''specified workspace does not exist''. I tried a few things that people were writing but none of the solutions were working.
I attached the photographs of the issues in appendix and I also put the zip file including my files that I used for the geometry model. I could not include the orthophoto because it's too big, but it should not be an issue for the export.
I hope that there is anyone around who know how to deal with this issue, would be a great help!
Thanks a lot in advance.
