Split lines at an intersection

In the Modify Features pane, Line Intersection splits straight and curved line features where they intersect and extends short segments to an inferred intersection. The angular pitch of z-enabled segments is preserved and new vertices are assigned interpolated z-values.

Attribute values are copied from the selected feature to the new features. Attributes constrained by attribute domains are determined by the domain split policy defined by the source geodatabase.

COGO attribute values for COGO-enabled lines are updated based on the type of edit you perform.

Note:

This tool is not available in 3D scenes.

1. On the Edit tab, in the Snapping group, enable your snapping preferences.

   Tip:

   As you sketch the cutting line, you can press and hold the spacebar to temporarily turn off snapping.

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

   The Modify Features pane appears.

3. Expand Reshape and click Line Intersection .

   The tool opens in the pane.

4. Click the two lines features you want to split or extend to an inferred intersection.
   1. Click one of the line features.
   2. Click the other line feature.
5. Check or clear Create new lines.
   • Check this setting when you want to preserve the existing lines and create new lines to complete an inferred intersection.
6. Hover over an actual or inferred intersection or press Tab to preview the possible intersections.

   A temporary point or dashed construction line indicates an intersection.

7. To split or extend the lines, do one of the following:
   • Click the point or the inferred intersection indicated by a dashed construction line.
   • Press Enter.

Note:

COGO attribute values for COGO-enabled lines are updated based on the type of edit you perform.

Type of edit	Lines	Arcs
Extended	All COGO field values are preserved.	All COGO field values are preserved.
Split	Direction field values are copied to the new line. Distance field values are recalculated for both lines.	Radius field values are copied to the new arc. ArcLength and Chord Direction values are recalculated for both arcs.
New	Direction field values are copied to the new line.	Radius field values are copied to the new arc.
