Using a separate layer outside of the Geometric Network to set barriers for the trace. The trace is a GP model that will eventually be published to server. The trace is a FIND_CONNECTED on a water network. we would typically use valves to stop the trace but are playing around with other options and scenarios. Placed barriers from a FGDB that would isolate an area and set it as Barriers in the "Trace Geometric Network" GP tool. The Trace GP completely ignores them and try's to trace the entire network. Do I not understand how this is supposed to work or am I doing something wrong? I have verified connectivity and our network is solid. What gives?
