When you modify a link using standard editing commands, the topology information associated with the link is not updated. Use this command to have the topology relationship information on the link updated. (If you modified the link using an AutoCAD Map 3D topology command, such as MAPLINKEDIT, the topology information was automatically updated and you do not need to use this command.)
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 object to update.
