Snapping to topology nodes

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.

You can create nodes in your topology for snapping purposes, such as by splitting a topology edge. If you display unselected topology nodes on the Editing Options > Topology tab, it is easier for you to see the temporary topology nodes.

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.

Steps:

1. 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.
2. Click the Snapping menu on the Snapping toolbar and click Use Snapping.
3. Ensure point snapping is enabled. If it is not, click Point Snapping on the Snapping toolbar.
4. Click the Snapping menu on the Snapping toolbar and click Snap To Topology Nodes.
