When I try to run Level DEM on the San Marcos tutorial data I get the error message: “Level DEM: System.Runtime.lnteropServices.COMException (Ox80040202): The index passed was not within the valid range. at ESRI.ArcGIS.Geodatabase.lFeature.set_ Value(lnt.32 Index, Object Value) at ESRI.APWR.ApHydro.ArcHydroOp.LevelDEM(ApLayers apLayers, lnt64 intFactor, String fillField, Double zUnitFactor, DoublefillElevOffse~ lnt.32 debug, ITrackCancel& trackcancel, IGPMessages& messages, String& exMessage) in C:\ Builds\HydroSolutions\ 10.3 ArcHydro\ Sources\ArcHydro Tools\ src\ApHydro\ArcHydroOp.vb:line 1002S” I followed the inputs given in the tutorial (using elev_cm as Raw DEM, NHDWaterbody as Lake Poly, Fill Elevation set to “none”, and offset set to 0). I followed all of the usual ArcHydro conventions (placed data in a relatively short and direct path, started from a fresh map, bringing in the DEM first, etc.). I tried this on two machines, one running ArcGIS 10.1, the other running 10.3, each with a fresh install of the latest ArcHydro builds with the same result. DEM reconditioning works fine, but I was curious to how Level DEM would perform. Any hints on what I might have overlooked?
