Split a feature

In the Modify Features pane, Split Split divides a polyline or polygon feature into two features and copies the attribute values to the new feature. Attributes constrained by attribute domains are determined by the domain split policy defined by the source geodatabase. When you split z-enabled features, the angular pitch for existing segments is preserved, and new vertices are assigned interpolated z-values.

You can create a splitting line across the feature or click a polyline segment without using a cutting line. A closed splitting line contained in a 2D polygon feature creates a nested part you can delete to create a hole.

Caution:

This tool does not split utility network features in this release of ArcGIS Pro. To learn more about editing a utility network, see Utility Network reference for editing.

Split with a cutting line

To split a polyline or polygon feature with a cutting line, click Split Split and select the feature. Create the cutting line across the feature using the tools on the construction toolbar, and click Finish. To create a hole, create a closed polyline in the feature.

  1. On the Edit tab in the Features group, click Modify Modify Features.

    The Modify Features pane appears.

  2. Expand Divide and click Split Split.

    The tool opens in the pane.

  3. To split editable features without selecting them, check Allow splitting without a selection in the pane and proceed to step 6.

  7. Create the splitting line using the tools on the construction toolbar.

    As you create the splitting line, the x, and y, coordinates appear in the vertices table.

  8. To apply your changes, right-click and click Finish Finish or press the F2 key.

    The selected feature divides into two features along the splitting line. A closed splitting line in the feature creates a nested part.

Split by clicking
