The Rebuild Network Topology tool was introduced with ArcGIS Pro 3.3 for utility network users and was also exposed as the Rebuild current extent option on the Validate dropdown. This tool and command provide the ability to rebuild the network topology in the current extent of an active map. This Add-In enables users who remain on ArcGIS Pro 2.9 and 3.1 to benefit from this functionality.
