In the Modify Features pane, Split divides a polyline or polygon feature into two features along a cutting line you construct across the feature, and attribute values are copied from the parent feature to the new feature. Attribute values constrained by attribute domains are determined by the domain Split Policy defined by the source geodatabase.
When you split a z-enabled polyline or polygon feature, the z-values of the existing feature and the cutting line are preserved. New vertices along the cut are assigned the z-values of the cutting line. To learn more about how editing tools modify z-values, see the 3D z-value reference for editing.
To split a feature, click Split , select the feature, construct the cutting line across the feature using the tools on the construction toolbar, and click Finish.
