When you select the "Next Upstream Protective Device" or "Next Downstream Protective Device" traces on the Electric Trace Toolbar and attempt to run a trace, you either receive no results or nothing happens. You may also notice that there is no "green flag" that shows up when you mouse over a line/conductor feature. However, other traces on the ArcFM toolbar work correctly.
The Next Upstream/Downstream Protective Device traces rely on a specific model name being assigned to the line features in your electric network. This model name is ELECTRICNETWORKEDGE.
Assign the ELECTRICNETWORKEDGE model name to your electric line features, such as your Primary/Secondary Overhead/Underground conductor features.
