Using Model Builder because tracing a geometric network in python is a pain. I have three feature classes (Switch, Fuse, Breaker) that all contain the field name [FacilityID]. None of the rows contain duplicate FacilityID values throughout all three feature classes. I want users to be able to enter a parameter value (i.e. S1234) and have model builder check if the row exists before going through the rest of the model.
If the [FacilityID] = 'S1234' does not exist in the Fuse feature class, do nothing. If [FacilityID] = 'S1234' exists in the Switch feature class, proceed with the rest of the model.
