A geometric network is a set of connected edges and junctions (nodes) along with connectivity rules that are used to represent and model the behavior of a common network infrastructure in the real world. Geodatabase feature classes are used as the data sources to define the geometric network. You define the roles that various features will play in the geometric network and rules for how resources flow through the geometric network.

Adding Geometric Network Trace to Map Using ArcPy
If running the script in foreground doesn't automatically add the output layer to your MXD, try using arcpy.mapping.AddLayer() to insert the layer into ArcMap:
import arcpy
arcpy.env.workspace = r"E …

What is Stopping Geometric Network Trace While No Barrier Specified
This looks very similar to a problem I'm currently having in my geometric network (sewer).
The problem could be disconnected or disabled features. To find these you will need to see zoom in at eac …

Identify larger diameter pipe flowing into lower diameter pipe in Geometric Network
I am doing this from memory as I don't currently have access to ArcMap, but I've done this task many times over the past 10+ years.
Create Upstream and Downstream Points:
Start by using the Feature V …

Filter edges in a geometric network trace?
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 h …

ArcCatelog 9.3 feature classes with annotation relationships allowed in a geometric network
You cannot have an annotation feature class as part of a geometric network, as it doesn't contain network data.
However, you can add feature linked annotation into the network feature dataset after c …

Identifying flow of a Wastewater Network
There is a button on the Utility Network Analyst toolbar (the same one you run your trace from) called Set Flow Direction. You need to use that to establish/calculate your flow direction before you c …

flag problem in network trace in arcmap
When we have situations like this we shift the lines slightly so they are never completely overlapped, by bending the ends slightly and then displaying them parallel (with a small almost negligible ga …
