Flow direction from Utility Network Edge Feature

EdwardBlair — Mon, 18 May 2026 13:08:50 GMT

In the Geometric Network using ArcObjects you can dig in to the details of a network edge and determine its flow direction -- which is useful in a number of circumstances, including if you want to determine the source side and load side of a given electric device (in a radial network). I can't seem to find an equivalent way to do this with the UN and the Pro SDK, but I could be missing something.

Any guidance here would be much appreciated.

Thx,

Hi Ed,

In the absence of IUtilityNetwork2.GetFlowDirection(edgeEID)... I think the recomended way now is to run a trace and iterpret the results.

Robert posted a sample a few months ago where you could derive the flow direction from the trace JSON.

Version 7/8 of the UN also has some interesting methods to work with and manipulate the digitized direction but I haent looked into that yet.
