I am having a problem running the Create Drainage Line Structures tool. I am running ArcGIS 10.6.1 and ArcHydro 10.6.. The tool generates the drainage line polyline, but does not create the output raster files. For inputs I am using a lidar derived floating point raster with 1 foot cell size and a polyline shapefile. The arc hydro IDs have been assigned using ArcHydro. The tool generates the following errors: Invalid parameters and Tool not licensed. I do have the spatial analyst extension enabled. Does anyone have any thoughts?
