Split a feature

The Split tool splits a visible feature into two or more features where you click it, or where a sketched line or the boundary of another feature crosses it. This tool is available in the Modify Features pane.

When you use this tool, consider the following:

• Splitting z-enabled features adds vertices with interpolated z-values and preserves the angular pitch of the split segments in 3D space.
• Attribute values from the original feature are copied to the new features. Attributes constrained by attribute domains are determined by the domain split policy defined by the source geodatabase.
• To split features into COGO lines use the Split Into COGO Lines tool .

The tabs appearing on the pane are described in the following table:
