Object data attached to closed polylines (above) and object data moved to centroids
(below).
AutoCAD Map 3D checks that the lines do not intersect each other, and that
the area is greater than 0. It then creates a centroid inside each selected polygon
or closed polyline and moves any object data or SQL link data to the centroid.
For an object shaped like a figure eight, AutoCAD Map 3D creates one centroid.
Centroids are created with a Z value of 0.
