I imported several hundred junctions using Modelbuilder, but not all junctions are attached to the pipes. I want to get rid of those junctions, is there a way to automatically find all orphaned nodes and delete them?
If you want to find all orphaned nodes then there is a tool for it, it is called Network Navigator. It can be found under View>Network Navigator>Click on Query (" > ")>Network Review>Orphaned nodes. This will select all the orphan nodes in the model, then select all these in drawing and hit delete.
