Align topology edges

In the Modify Features pane, Align Edge Align Edge can close gaps between edges of topologically connected polyline or polygon features when you enable a topology and click an edge. Edges highlighted as dashed lines are not modified.

This topic shows you how to use map topology to close gaps between topologically connected geometry. For steps to trace a feature and close gaps between complex boundaries, for example between a stream and a forest boundary, see Align features to a traced line.

Align Edge

To close a gap between topology edges, enable a topology, click Align Edge, hover over the gap until the edge you want to align highlights as a solid edge, and click the edge.

  1. On the Edit tab, in the Manage Edits group, click the topology arrow and enable Map Topology Map Topology or a geodatabase topology.
  2. On the Edit tab in the Features group, click Modify Modify Features.
  3. In the Modify Features pane, expand Align and click Align Edge Align Edge.

    The topology graph highlights in the map.

  4. Hover over the edges until the edge you want to edit highlights as a solid edge. Edges highlighted as dashed lines are not modified. If an edge does not highlight as a solid edge, it cannot be modified, and you must click a different edge.

  5. Click the edge.

    The solid edges snap to the dashed edges spanning the topology nodes.
