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
