Enabling snapping to topology nodes allows you to snap to a node in a map topology or a geodatabase topology. You might do this when you need to move parts of topology edges or snap to a location that is not an actual vertex in the feature.
To enable topology node snapping, point snapping needs to be enabled first, and the map must contain either a map topology or geodatabase topology with the layers you want to snap to participating in it.
- Make sure you are in an edit session and have either a map topology or geodatabase topology containing the layers to which you want to snap.
- Click the Snapping menu on the Snapping toolbar and click Use Snapping.
- Ensure point snapping is enabled. If it is not, click Point Snapping on the Snapping toolbar.
- Click the Snapping menu on the Snapping toolbar and click Snap To Topology Nodes.
