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.

enter image description here

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.

Are you able to edit your network features? If so the easiest way to selectively trace features in a geometric network is to set them as Not Enabled (Enabled = False).

Every network feature will have a field called Enabled which you can set to True or False to indicate whether you want the trace to traverse those assets or not. If you select all your non-Storm assets and set Enabled to False, and then select all Storm assets and set Enabled to True, your trace will only run on your Storm assets.

enter image description here

If you already have different features with Enabled set you may need to copy your network out to another database or perform your edit and trace in a version. Once you've completed your trace you can always revert your Enabled values back.

  • Thank you for your answer! I was definitely over-complicating this problem. It takes forever to field calculate rows to disabled for the traces and back because of the size of our network, but this definitely solves the problem. – Priscilla Sep 22 '16 at 13:15
