Creating Closed Polylines from a Polygon Topology
Concept Procedure Quick Reference

You can create closed polylines from a polygon topology. This is useful if you want to give data to an AutoCAD user so the user can hatch polygonal areas.

While creating closed polylines from polygon topology, you can create a group containing all the elements of complex areas, such as islands. If the islands themselves have nested islands or other polygons, these nested polygons will form a separate grouping automatically, creating different levels of grouping. If two or more inner polygons are not nested but share the same outer boundary, they will be treated as one group.

You can manipulate grouped data with the GROUP command. For more information, see GROUP in the AutoCAD Help.

You can also copy the object data and the external database links held in the centroids to the closed polylines.
