You can model the pipe connections as devices.  You do not have to use stormwater junctions.  Can you provide a schema only UN and I can look into why the snapping is not working.   Snapping is not enabled for Structure Junctions to Stormwater Pipes, as you cannot create a rule for this.  You can always right click and select snap to though. ...

Two isolation traces are the only way that I know how to achieve this. ... View more

If you want to copy the Manhole elevation attribute to the Pipe, then I would look at the Spatial Join Templated Attribute rule.  You should be able to configure it for your needs.   https://www.esri.com/arcgis-blog/products/arcgis-pro/data-management/attribute-rules-generate-spatial-join ...

Edit, We do not have an Attribute Rule to set the Z's or attribute of the From/To elevation from the snapped feature.  The rule you posted just calculates the slope of the line via the From/To Elevation.  There is a rule to Set the From / To elevations from the Z.  We rely on ArcGIS Pro and snapping to copy the Z to the geometry.  How did you draw the sewer main?  Was it snapped to the manhole on create?  Did the manhole have a Z?     ...

Are you using the pressure zone tier? If so, running your isolation trace on that tier could speed things up. How many controllers do you have on the system tier? ... View more

Would be interested in seeing the same batch trace run from a script, outside pro. 30 secs a trace is not good. Nothing batch trace can do about that. I think it is the gp tool overhead of running inside pro. You have 9 maps and one active. The trace is communicating with those maps. Try it in pro with no maps, you will see a huge improvement ...

I reviewed the code for Batch Trace and I take back this statement"Batch trace can use the resulting lines and remove them from the trace starting points to reduce the number traces required. " Batch trace does not have this skip logic, but Build Starting Points does.  So you could run Build Starting Points and an Isolation trace to build out the starting points to trace the system.  Then run Batch Trace with that reduced set.  I will add an issue to expose that logic in Batch Trace too.  ...

Also very interested in why Batch Trace is taking 15 seconds a feature.  If you turn on debug mode, we can get a better idea of what is going on.   Open ArcGIS Pro Open the UtilityDataManagementSupport toolbox Open any tool in the tool box.  This loads the udms module from inside that toolbox into python/memory Open a python command prompt enter the follow:   import udms udms.logger.setLevel('DEBUG') Run Batch Trace ...

Batch trace can use the resulting lines and remove them from the trace starting points to reduce the number traces required. Now doing this may lead to some inaccurate results. Such as a larger area isolates pipes that could be isolated with a different set of valves. Each trace result is stored in its own file, so you would just process the results after complete. The only way we thought to reduce it was to skip calling gp trace and call the trace rest end point directly, which eliminates the gp overhead and multithreading the traces. ... View more
