Hello everybody

I started working in a project on ArcGIS, when i used "LongestFlowpath" tool (in HEC GeoHMS) I got an error with this message :

System.Runtime.InteropServices.COMException (0x80040215): Exception from HRESULT: 0x80040215

   at ESRI.ArcGIS.Geometry.IRelationalOperator.Contains(IGeometry other)

   at ESRI.APWR.ApHydro.ArcHydroOp.ComputeLongestFlowpath(ApLayers apLayers, Int32 debug, ITrackCancel& trackcancel, IGPMessages& messages, String& exMessage, IRaster costRaster)

Failed to execute (LongestFlowpath).

Does anyone has any idea what might have caused it?

I would really appreciate your help

Thank you very much

The cause could be a number of things. Working with your mxd and other data on your local box and not over a network saves time and eliminates errors. There are several tips at https://community.esri.com/thread/43771 that might be helpfull.
