Hello,

I am working with HecGeoRAS trying to create my feature classes. I started with the RIVER feature class. I am working with a big river network of approximately 359 reaches. I have the designed of this network using polylines in a shp file and I am trying to introduce these data in the attribute table of the RIVER feature class.

I am looking for a function in ArcMap 10.3.1 that recognise the ID from and ID to for each of the polylines, because make it manually is very time consuming.

I hope you understand my question.

Thanks!

Sara
