These information are with geometric network system tables (topology tables). Using ArcObject you can easily query those information (from , to node) an assign them to the edge feature class. But no function exists with arcpy or python to query these information. Therefore you have to put the geometric network aside and use spatial relationships ...

This is a late answer and you may have already solved your problem. However there is no relevance between geometric network and editor tracking. they are two separate things. The snapshot you have shared indicates that you have enabled editor tracking with this feature class. If you can't see the dates fields, you may have hide them. So remove the layer and ...

First you have to do a trace downstream from the discharge point. Make sure the return result of the trace is set to be a selection set. After this trace you have a set of selected river features. Then you must convert your polygon layer to a line layer using "Polygon To Line" tool. Then you have to use the Intersect tool to intersect the selected rivers ...

Output Group Layer Name is the name of the group layer that will store the results of the trace as a selected set. Based on your scenario, there must be one feature layer (e.g. SourceFeatureLayer) inside that group layer that you have to a get a reference to to export it to a Feature Class. You should use the name of output group layer concatenated to the ...

If you setup a weight based on the lenght of your network edges (what you have done so far) then you will get (ABCDE) path. If you need to get AF path, then you should setup a based on the number of junctions along the path. To do so, create a weight (Integer), and assign a numeric field of your Junction FeatureClass to that weight. Let say you have a ...

Have you set the flow direction of the network? You need to run this tool. The Trace upstream should then behave. For the record I had to set the weight field (which was length) to be against the digitized direction to make the trace follow the shortest route to source. I am unsure how this would influence a trace in a more complex scenario such as a river ...

You can use Trace Geometric Network gp tool and set the Junctions as flags

If you have set the flow direction as @ChrisW mentions then the polylines should be flowing in a source to sea direction. Place your flag at the green location then using the Utility Network Analysts tool bar set Trace task to Trace upstream and solve. The trick here is before you do the trace go into the options section under the Analysis dropdown on the ...

You could use network analyst. First create a network out of your pipeline files. Then Load a closest facility problem and drop your incidents at the end of each pipeline you want to measure. Your facility will be the main facility. In the accumulation tab under properties of the closest facility in the TOC you can set your accumulation to feet or miles or ...

I am using ArcGIS-DeskTop 10.2 for reference. In ArcToolBox go to Analysis tools. Inside of the Proximity envelope there is a tool called 'Generate Near Table'. This tool will generate a table output containing the standard OBJECTID field, an IN_FID field for the input feature, NEAR_FID for the near feature input, a NEAR_DIST field for the distance the near ...
