If you have polygon objects
or closed polylines with data attached to them, you can create centroids
and move the data to the centroid. This is useful:
- After you import or digitize objects.
- Before using editing commands such as Drawing
Cleanup, Boundary Break, or Boundary
- When working with topology.
Object data attached
to closed polylines (top) and object data moved to centroids (bottom).
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
Centroids are created
with a Z value of 0.
