We recently ran at work into this model created by ESRI for the rivers in the US:
In order to make QA checks we are trying to embed this sort of model into a geometric network of sewage which has about 5000 line features.
We tried to use the add-in attached to the code (ExportHydroNetwork) in order to apply it on the network, but it didn't even appear on the add-in manager after connecting to the folder (arcmap 10.3)
What are the parameters that this add-in requires for work?
Does it, for example, need a field that classifies level of each line segment?
Or maybe it requires modification in the arcmap environment?
