Preparing to edit topology by labeling features, setting snapping, and changing a topology symbol

Labeling features can make it easier to identify the ones you're supposed to edit. Snapping makes it possible to make precise edits by establishing exact locations in relation to other features. The snapping environment allows you to snap to parts of features, to an edit sketch, or to topology elements.

When you edit a topology, the default is for the selected edges and nodes to be drawn. If you need to create temporary topology nodes (for example, for snapping purposes), you should turn on drawing for unselected topology nodes as well.
