Hi,
I'm trying to extract flow paths from a DEM using the Generate Flow Path tool in ArcHydro Tools>Point Characterization. I have generated all required input datasets using Basic Combined Terrain Processing Model Builder in ArcHydro Tools>Terrain Processing Worflows. The error I receive when I run this tool says "DrainID does not exist for DrainageLine!". I think I'm missing steps on the watershed analysis part, but I can't figure out what it is and which tools to use.
Any help is greatly appreciated. Thanks.
