Set Structure feature as starting point

PierreloupDucroix

Hello,

I cannot find if a feature from the structure network can be set as a starting point to trace the network.

The documentation tells that only features that are part of the network topology can be used, but is it the case for structure features ?

I tried to include structure elements in my subnetwork definition, but when trying to trace from a structure, it always fails with error "no subnetwork controller found".

Thanks

If you are trying to actually trace the structure network, not a domain network, you can use a Connected Trace or Shortest Path Trace.

Hi,

thank you for your answers. I know that there are some workarounds, like using the "select by association" from UDMS first, then trace from the resulting feature into the domain network. I was wondering if it was possible, mainly because it is not explicitly told in the documentation. And because you can trace the domain network and get features from the structure network.

@RobertKrisher here is my use case :

I have ducts that contain electric cables. For each duct, I need to get information about the first upstream and downstream protective devices of the cable and get their names into a field. In order to help the user get these values, I created a script that automates the process, thus tracing from the structure network to the domain network. But indeed, the tracing from the structure to the domain only consists in getting the associated cable.

Can you provide an example of the use case you are trying to solve by tracing a structure?

Tracing allows the utility network to analyze the connectivity of the network topology. Only features in a domain network have connectivity that you can trace. When analyzing structures, the system performs the network analysis on connectivity then looks at the attachment and containment associations they have with the resulting network features how they support the connectivity of the network.

Off the top of my head I can think of a couple of purely structural type analysis, so I'm curious to hear what your use case is.

it would only work for tracing the structure network, not a subnetwork.
