I've been using the Geometric Network tools for quite sometime now to trace electric distribution networks for my job and all of a sudden when try to trace the circuits and connected features from each particular transformer the trace won't work and the features aren't selecting. I have it set to Find Connected and the box in the Analysis dropdown and options is set to Selected Features. I can't figure out what has gone wrong. Also there hasn't been any ArcMap update since I'm still using 10.3.1.
Can anyone suggest a fix or know what's wrong?
