Reshape a topology edge

In the Modify Features pane, Reshape Reshape can modify topology edges when you enable map topology on the Edit tab. The new linear shape you draw across an edge replaces existing edges where the first and last segment cross or touch one or more topologically connected features.

For example, you can draw a polyline across a shared boundary between two parcel boundaries and make lot line adjustments, or draw a line across several lots and trim them uniformly for a street widening project.

Reshape edges

Reshaping an edge enables you to make complex changes to coincident boundaries that need to remain topologically connected when you finish your edits. When multiple features are selected, you can refine the selection in the pane and choose the features to be modified.

  1. On the Edit tab, in the Manage Edits group, click the Map Topology Map Topology drop-down arrow and enable map topology.
  2. On the Edit tab in the Features group, click Modify Modify Features.

    The Modify Features appears.

  3. In the pane, expand Reshape and click Reshape Reshape.

    The tool opens in the pane.

    • Click Toggle Selection Blue button to add or remove a feature from the selection.
    • Uncheck a feature to temporarily disable editing for an individual feature.
  7. To manage the selection, right-click a feature and use the following commands:
    • Flash Flash—Flashes the selected features in the map.
    • Zoom To Zoom to Selected—Zooms the view to the selected features.

    • Only Select This Unselect—Removes all other features from the selection.
    • Unselect Clear Selected—Removes the feature from the selection.
  8. Using construction tools on the editing toolbar, draw the new edge over the existing edge so that it crosses or touches the edge in at least two places.
    Note:

    The first and last segment must cross or touch one or more contiguous features.

  9. On the editing toolbar, click Finish Finish or press the F2 key to apply your changes.
    Note:

    If your edits break the topology graph, the message Edit operation failed Error appears, and your changes are canceled.
