Hello everyone,

Environment:  ArcGIS 10.7, ArcSDE 10.7 in a Ms SQL Server database.

We set up our geometric network with  Flow direction  "With Digitized Direction". After running the tool, the whole Geometric Network had a direction.   Now when we digitize new lines with the regular editor tool, we do not see the flow direction represented in the new lines, it shows as UnInitialized . Is there anything else we have to do in ArcMap  to see flow direction in new digitized lines.

# Process: Set Flow Direction

arcpy.SetFlowDirection_management(SewerNetwork, "WITH_DIGITIZED_DIRECTION")

It looks like you may have to set it when you add new features; About setting flow direction—ArcMap | Documentation 

You must set flow direction whenever you do the following:

I am not sure if it does it on-the-fly or live.

Hi George

In our case we added features to the geometric  network.

This same links says  that "You can use ArcMap … to maintain flow direction in your geometric network" 

But I do not understand how. Is there a tool in ArcMap to run the  "Set Flow Direction", after an editor adds additional points or lines?

In our environment a regular editors  performs these operations:

 - Add or remove features from the network.

- Post and Reconcile from his/her child version to QA version

So as part of the editor tasks we need to include a  "Set Flow Direction"

How can we do that?

Here is the link to Setting the flow direction—ArcMap | Documentation . You could also have them run the GP tool you reference in the OP; Set Flow Direction (Data Management)—ArcMap | Documentation
