Identify Isolating Valves

khem1000 — Thu, 11 Sep 2025 14:22:59 GMT

Hi, I have configured an isolation trace in Pro against my UN, which seems to work i.e. it returns all the devices (valves, service connections etc) and waterlines that are in the trace.

I have configured it to include isolating features

From the results I can identify the properties impacted. But I would also need to list the isolating valves to close. The results include other valves in the trace too which have same attributes as the isolating valves.

@RobertKrisher , any suggestions how I can identify both the impacted properties and the isolating valves from trace results?

The results are returning only operable valves.

You have to run two traces, one with Include Isolated Features and one without that checked. Without it checked, it will return the features that match the filter barrier(isolating valves)

Thanks. I thought I may have to do that.

So just to confirm, there is no way to identify the isolating valves from the result when I check to include the isolating features?
