Hi,

I have all the required input datasets for Generate Flow Path tool but when I run this tool, it give me this error message:"DrainID does not exist for DrainageLine!". I don't know what step I'm missing in terms of adding DrainID to my layers. I used ArcHydro ModelBuilders from ArcHydro Tools>Terrain Processing Workflows to generate the input rasters and feature classes.

Thank you.

There is one geoprocessing tool in the Arc Hydro Toolbox in the Point Characterization toolset called Generate Flow Path.
It takes as input the source points to trace, the flow direction grid as well as the Catchment and Drainage Line feature classes to speed up performance. It generates the flow paths. You may want to check it out.

How should I generate catchment and drainage Line feature classes?
