Understanding Common Subnetwork Errors in an ArcGIS Utility Network (Pt. 1)

pt_instructor

You have edited a segment of your Utility Network, followed by a successful validation of its network topology. Have you then been surprised -- and perhaps a little daunted -- when subsequent processing, such as running Update Subnetwork or a Trace, returns a complex error message implicating the features you carefully edited? Observe common causes of this situation in this video series. This first video was recorded with ArcGIS Pro 3.1 in May 2025.  For further training on utility networks, check out Esri's Working with Utility Networks in ArcGIS https://go.esri.com/utility-course.
