Connectivity Rules Questions

testnew — Tue, 23 Sep 2025 07:22:17 GMT

Hi ,

I am working on adding connectivity rules to an empty Utility Network DataSet. I found that might have some error.

I used the Add Rule Tools to Add the first connectivity rules into UN Dataset, after successfully add the rule, I found that in the UN Propertity, the rule's FROM ASSET TYPE and TO ASSET TYPE is exchanged.

Then I used arcpy to add the same connectivity rule to UN Dataset, error comes that the rule is existing.

What's reason about that? I appreciate any help with this.

I do not know why it swap it, but it does not matter. EJE the order of edges do not matter.

Hi,
I encountered the same problem. Is it possible that this is a software bug? Or is this just how UN is designed?

The order of the from/to edges doesn't matter, so because you've added the rule to the UN using the GP tool it will fail when you attempt to create a duplicate rule using Python. If you add a new rule using Python it will work.

Finally, if you have many rules you need to add you should consider creating a CSV defining all of them then using the Import rules tool to import them all at once.
