Similar to Ben Coakley's issue about "Function Outputs", there is practically no documentation that I can find about how to utilize the results of a trace (SELECTION option) using arcpy scripting. Basically, I want to save the selection to a layer so I can do further tracing or analysis on the derived selection. There should be an option similar to AGGREGATED_GEOMETRY which saves NON-AGGREGATED results. I don't see a rationale for aggregating geometry anyway as it produces just a single mult-part feature which seems useless to work with. Will exploding the aggregated geometry always maintain flow direction of the individual features? Even so, if there were important attributes on the original network, they would now be lost in the aggregated dissolve, which means you can't do any attribute queries or further selections on the aggregated output. By comparison, the old TraceGeometricNetwork function allowed you to work with the Group Layer output and save the results to a separate feature class with the attributes intact. I would like to see this functionality in the new Trace function (or at least the ability to save the selection with original geometry and attributes as optional output).
