Use Erase Dangling Objects to locate an object with at least one end point that is not shared by another object, and erase the object.
The Erase Dangling Objects action searches for and deletes all line, arc, and polyline dangling edges, and nodes. Dangling objects do not include closed polylines.
Dangling objects are removed.
A dangle is often caused by inaccurate digitizing where an object extends beyond its intended intersection with a target object. Use Break Crossing Objects before using Erase Dangling Objects.
