Terminal connections more than one line

DanieleChiara — Wed, 24 Jan 2024 11:10:49 GMT

Hi all i have a doubt:

i'm currently working with an GAS UN custom and i have defined a direction terminal with 2 terminal (Input and Output). I notice that i can have more than one line for both Input and output. Is this the correct workflow? I initially thought that I could connect only one line to one terminal, but it seems that I might have missed some rules.

As you can see, there are no topological or subnetwork errors.

Thanks

Hi @MikeMillerGIS may you clarify is this type of editing is correct or it is a bug?

This is allowed, nothing restricts the cardinality.

@MikeMillerGIS there is a way to "force" only 2 line in a certain point? not only for the terminal i mean in general. In this specific case the PT->Modify Terminal Connections geoprocessing don't connect in the right way the line if the rule are not restrictive (if one point can connect in any terminal the tool don't follow the direction but make the connection at the first available terminal). i have to develop a custom way to connect correctly the terminal but i think can be usefull for all users that make the porting to UN.

Without an attribute rule, no.

We have created an auto assign terminal Attribute rule that does have this logic though. It will not assign a terminal if it is already used - https://community.esri.com/t5/arcgis-utility-network-documents/automatic-assignment-of-from-to-terminal-values-on/ta-p/1307198

but if there is only one rule to that terminal, then a value is not required and it will connect with no error.

@MikeMillerGIS so for porting there is no way to force.

by the way i try your tool but it works ONLY when you have different rules for the line that can be assigned on upstream or downstream. If you have the same role for both terminals the tool assign every line on the first terminal avaliable. This is an error for common usage, in my opinion, the tool have to associate all terminal available using the roles AND the directionality. Obviusly if the flag for digitalized direction is set to true.
