Topology Cleanup ensures data integrity, which is essential for creating topology layer and performing topology analysis. Topology Cleanup tools work on linear elements such as lines, line strings, curves, arcs, complex strings, and both simple shapes and complex shapes. 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 Preferences dialog box. 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.

Key-in: FENCE DROP COMPLEX

To convert all linear elements to line strings before cleaning, use the following key-in: FENCE STROKE
