If you have data attached to polygon objects or closed polylines, you can create centroids for the polygons or closed polylines and move the data to the centroid.
To create centroids for polygons and closed polylines
In the Create Centroids dialog box, specify whether to create centroids for all closed objects or only for selected closed objects. If only for selected closed objects, select those polygons and closed polylines.
Tip:
Use Quick Select to view and filter the object type as you select objects.
Specify the layer on which the centroids should be created.
Specify the block to use for centroids, or use ACAD_POINT.
