Flow Direction does not show in new digitized lines

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:
Create a new geometric network.
Add or remove features from the network.
Reshape features so as to change the network connectivity.
Connect or disconnect features.
Add or remove sources or sinks.
Enable or disable features.
Reconcile a version

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
