Use the Create
Centroids dialog box to create centroids in the middle
of selected closed polylines or polygons, and move any object data
or SQL link data from the closed object to the centroid.
When you use this feature, AutoCAD Map 3D checks
that the selected polygons and closed polylines are clean; that
is, that the lines do not intersect each other, and that the closed
object has an area greater than 0. Centroids are created with a
Z value of 0.
If the closed object
has holes, the centroid will be placed in the center of the enclosed
area, regardless of whether it falls within a hole or not. For a
'figure eight' polygon, AutoCAD Map 3D will create one centroid.

the centroids and what point or block to use for centroids.
- Create on Layer
Specify the layer for
the new centroids. Click the down arrow to select from a list of
layers in the drawing. If the layer you want is not listed, it may
be frozen or locked. To create the centroids on a new layer, click Create
