I created a network diagram from a Trace Network. Then tried to apply updates made to trace network features to the network diagram. While attribute updates are applied and show up on the network diagram elements, newly added features do not. I'm probably missing something. Here is my workflow. 1. Network diagram fragment. 2. Add new features to source Trace Network (shown as selected) 3. Run the "Update Diagram" GP tool from the map. There is no change to the network diagram. Any suggestions would be much appreciated. Thanks, Ed

Hello - In our current (ArcMap/GN) implementation we have a process that runs nightly uses version differences to detect any features that have been deleted from SDE.Default in the previous day. Any features found are written to a "DeleteHistory" file geodatabase. Features are never removed from the DeleteHistory database. I won't enumerate, but there are all kinds of cases where a feature/features can get unintentionally deleted. The process has certainly saved my bacon. It seems like branch versioning will retain history of what has been deleted... up until the point where we need to perform a "prune". At least it seems so. My understanding is that "prune" will remove any archived features no longer associated with a version -- meaning it will remove rows that would otherwise describe what was deleted. If this is true, has anyone developed processes to retain delete history beyond the "prune" operation? We're thinking that this *might* be accomplished simply by creating a file geodatabase snapshot before the prune occurs.. though, if we have to search back over multiple "prune" operations we would have to search over multiple FGDB snapshots. Any thoughts or suggestions would be much appreciated. Thanks, Ed

Google Gemini says I should be able to get a reference to a Trace Network using the following code. TraceNetwork traceNetwork = gdb.OpenDataset<TraceNetwork>("MyNetwork"); (see below) I don't see "TraceNetwork" as a valid definition for a geodatabase object when I try this. Am I missing something, or is there another way to do this? Thx, Ed

Hi - Our source data has *many* cases where a surface structure (pedestal, junction box, cabinet, etc.) is connected to an underground structure line (conduit or duct bank) at a mid-span vertex. We were advised by one party that retaining this configuration (allowing connections to "any vertex") in the UN could have adverse downstream consequences. In limited testing in a test mobile geodatabase, this configuration seems to work fine. We create the junction, re-build the subnetwork, move the junction and have the structure line adjust its shape, re-build the subnetwork, and all seems to work hunky dory. Should we be concerned about pursuing this path? The alternative would be to split *many* UG structure lines either in the source or the migration process, which we would prefer not having to do. Any feedback would be much appreciated. Thanks, Ed

Sorry Mike.... I'm an idiot. I had my query on GlobalIDs screwed up. The issue was not with the Pressure Recording device, but rather with Test points... which were *not* in the subnetwork definition. Thanks a bunch for your reply. Sometimes it takes saying the problem out load, or wring it out, to actually fix it. Ed

Hi Mike - Thanks for the reply. I thought it *had* to be in the parent tier to be present in the "child" tier. Anyway, yes, the "Pressure Recording Device/Unknown" is present in both the "System" and "Pressure" tiers. Ed

All - Sorry if I am missing something simple here, but when I try to update a pipeline isolation subnetwork I get an error that process encountered an "invalid device" when I'm certain that device is present in the subnetwork definition. Here are the details. First, here's the error message: I then search for the offending features in the PipelineDevice class using the GlobalIDs listed in the error. Here's what I get (why there are 5 GlobalID values in the error and only one feature returned on the query is another question... but one step at a time.) The offending feature's Asset Group is "Pressure Recording Device" and Asset Type is "Unknown". So I check the subnetwork definition and see this: The Asset Group/Asset Type seems to be present in the Isolation tier subnetwork definition. Any pointers on what I am missing would be greatly appreciated. Thanks, Ed

NM. I should have Googled before posting. Apparently this is an ArcPro SDK convention that indicates the table is defined with traditional versioning. Ed

Hi - I'm just trying to understand what's going on here. I have a stand-alone table from an Oracle database in my TOC named MAXIMO.ZXQSERVPOINT. See below. When, in code, I iterate through the tables present in the TOC the name is returned as "MAXIMO.%ZXQSERVPOINT". See below. What's the deal with the "%" ?? Any info would be appreciated. Thx, Ed

Of COURSE .... its in the next release. You're killing me man. Anyway, thanks for the info. Ed

Hey @RobRob and/or @RichRuh - As documented in the article you reference above, the export subnetwork JSON describes an "un-directed graph" of the subnetwork. Without writing one's own equivalent of a ForwardStar, is there some way to define directionality on this? Currently in the UN we use the ArcFM FeederTrace to create a device hierarchy for a feeder. That is, each device knows its parent device. I was hoping to create the same from a subnetwork export, but am currently stuck on the "un-directed" part. Thx, Ed

Thanks Robert - Our use case is this. We currently represent substation internals in a geometric network separate (spatially and logically) from the distribution network. As an initial step in our UN journey the thought was to include distribution features in the UN network, but put substation internals into a simpler trace network. With a long-term goal of incorporating the internals into the UN. Seems to me, knowing what I've discovered about the trace network, this strategy will not work. A better approach for us may be to include the sub internals in a separate utility network. But we're still mulling this over. Ed

Not as far as I can tell. We need to operate on a set of selected features and determined what they are connected to, with the possibility that they are not connected to anything. Someone had the idea that we could use a Trace Network for this, but it looks like that will not work. Ed

Again.. I'm not looking for how to perform a trace. I see that. What I'm looking for is a way to examine a selected feature that participates in the trace network and discover what other features it's connected to... without performing a trace. The equivalent of the GN: ISimpleJunctionFeature::EdgeFeature Ed

‎06-02-2026

Thanks for this. I've actually seen the post. But its not really what I'm looking for. I should have been more clear. In the GN you can get a feature cast it to a network object, like a simple junction, and from that find out what its connected to. You can take similar steps to find what connected to a given feature in the UN. I need to do the same for features in a Trace Network. Thanks again, Ed
