While trying to generate flood map using HEC-GeoRAS for the data I imported from HEC-RAS, the following error occurs. Can anyone help me how to resolve and continue?
Failed to create water surface tin:
Runtime.InteropServices.COMException (0x80040833): TIN internal process error.
At ESRI.ArcGIS.Geodatabase.TinClass.AddFromFeatureClass(IFeatureClass PFeatureClass, IQueryFilter, IField pHeightField, IField p TagvalueField, esri TinSurface Type Type, Object& pbUseShapeZ)
At HECGeoRAS. clsMFloodWaterSurface.CreateWSTin(FeatureClass pSrcFC, IFeatureClass pClipFC, IFeatureClass pWorkFC, String s TINName, String sProfileName)
Best,
