Hi everyone, I am using ArcGIS 10.6 and HEC-GeoRas 10.6. I need to create a GIS project; first I run my steady simulation in HEC RAS, exported all data from HEC-RAS and then exit the program. Next, in ArcGIS with GeoRAS I convert SDF to XML file, set up my layer, create the new analysis and do a water surface generation, all good without problems. Finally, when I choose: "Floodplain delineation using rasters" I get this error: System.Runtime.InteropServices.COMException(0x80041098):ERROR 010151: No features found in C:\........\Steady_PF\fdtemp.shp. Possible empty feature class. at ESRI.ArcGIS.GeoAnalyst.RasterConversionOpClass.RasterDataToPolygonFeatureData(IGeoDataset dataset, IWorkspace pWorkspace, String name, Boolean weeding) at HECGeoRAS.clsMFloodGRIDIntersection.GridToPolygon1(IRaster pRaster, IGeoDataset pGeoIn, IWorkspace pWS, String sName, Boolean sWeeding) I can't solve it, can somebody help me please? Thank you so much! #hec ras #hec geo ras #geo hec-ras #hec-ras #hydro #flood mapping #HydroTools
