Reshape a topology edge

Reshape Reshape can reshape shared topological boundaries. If map topology is turned on, the linear shape you draw across an edge replaces existing topology edges where the first and last segment cross or touch one or more topologically connected features. This tool is available in the Modify Features pane.

When multiple features are selected, you can refine the selection in the pane and choose the features to be modified. If your edits break the topology graph, an error message appears in the pane and your changes are canceled.

To reshape topology edges, complete the following steps:

  1. On the ribbon, click the Edit tab, turn on Map Topology, and show the Modify Features pane.
    1. In the Manage Edits group, click the Map Topology Map Topology drop-down arrow and enable map topology.

  4. Click Select one or more edges Select Topology and click the edge you want to reshape.
  5. To split the connection between one or more topology edges, disable editing for the feature or turn the selection off in the selection tree view.

    • Click the feature button to turn the feature selection on or off.
    • Click the feature name to flash the feature in the map
