In the Modify Features pane, Split divides a polyline or polygon feature into two features along a splitting line you create across the feature. A closed splitting line in a polygon feature creates a nested part you can delete to create a hole. The angular pitch for z-enabled polyline segments is preserved, and new vertices are assigned interpolated z-values.
Attribute values are copied from the parent feature to the new segments. Attribute values constrained by attribute domains are determined by the domain Split Policy defined by the source geodatabase.
To split a feature, click Split , 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.
- On the Edit tab in the Features group, click Modify .
The Modify Features pane appears.
- Expand Divide and click Split .
The tool opens in the pane.
- To split editable features without selecting them, check Allow splitting without a selection in the pane and proceed to step 6.

- On the Edit tab in the Snapping group, enable your snapping preferences.
- Press and hold the Spacebar to temporarily turn snapping off.
- 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.
- To apply your changes, right-click and click 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.
