Use this command to have the topology data on the polygon updated.
When you modify a polygon using standard editing commands, the topology data associated with the polygon is not updated. (If you modified the polygon using an AutoCAD Map 3D topology command, such as MAPPOLYADD, AutoCAD Map 3D updated the topology for you.)
Respond to the prompts:
Enter the name of the topology to modify. To display a list of all loaded topologies, enter ?.
Use any selection method to select the centroid of the polygon to update.
