I am using ArcGis 10.3 and am trying to trace a geometric network from a catch basin to a catch basin lead to a mainline ultimately to a storm pond.

  1. Flow direction is set correctly using digitized direction
  2. Traces when the flag is placed at the mainline manhole, the tracing works flawlessly
  3. Problem occurs when I trace from a catch basin, it will highlight to the lead by stop at the mainline, what could I be missing?

My mainline and CB leads are in the same feature class. CB points and manholes are in the same point feature class.

CB and MH Points:Simple Junction

Mainline and CB Leads fc: Complex Edge

  • Newly built network with no new edits, but I will give that a shot. Jul 16, 2018 at 17:39
  • Did not work the same problem persists Jul 17, 2018 at 14:13
  • What type of junction feature is located where the tracing stops ? Is it enabled? Jul 17, 2018 at 14:16
  • Connecting a line to a line (as shown above) Enabled: Yes (TRUE) Jul 19, 2018 at 17:15

Found the answer, I needed to add a junction to the line where it attaches to the mainline.
