Topology Cleanup
You can find the Topology Cleanup tools in the Topology ribbon group of the Map Topology workflow. The tools eliminate duplicate and similar line work, close gaps between element end points, segment crossing elements that do not intersect, eliminate dangling elements, and thin unnecessary vertices from line strings and curves.
The cleanup tools preserve the element types lines, line strings, curves, and circular arcs (non-circular arcs are also preserved when segmenting elements with a zero tolerance). Any arcs or curves contained in complex strings or shape elements are approximated with line strings using the stroke tolerance defined in the Topology category of Preferences dialog. As a result of stroking complex elements and shapes, the integrity of any connected strings in these element types will not be preserved. To maintain arcs, curves, and connected strings within complex elements and shapes, drop the complex status of the elements before using the cleanup tools.
To convert all linear elements to line strings before cleaning, use the key-in: FENCE STROKE
