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.
