I need to trace a geometric network of sewer pipes, but I'm only interested in storm pipes. More specifically storm pipes that connect directly to a starting flag, and not those downstream/upstream of another pipe-type. Each starting flag might have several pipes connected to it of different types (e.g. sanitary, storm, CSO, etc.). Unfortunately, I can't query out the storm pipes because traces only accept geometric networks and not feature layers.
I've been reading about "in_edge_along_digitized_weight_filter" (in trace geometric network tool), but I can't figure out how to use it. The drop-down box is empty for this option. My geometric network was not built with weights, so I'm guessing that's probably why.
I would like to avoid rebuilding the geometric network if possible.
