To Update a Topology

Objects in a topology have relationship data stored in an object data table. If you modify the objects, the topology data on the objects is updated.

To update a topology

1. Verify that the topology containing the objects to update is loaded.
   • To update nodes in a node topology, in Map Explorer, right-click the topology name. Click Update. To update nodes in a network or polygon topology, type MAPNODUPD on the command line.
   • To update links in a network topology, in Map Explorer, right-click the topology name. Click Update. To update links in a polygon topology, type MAPLINKUPD on the command line.
   • To update polygons links in a polygon topology, in Map Explorer, right-click the topology name. Click Update. You can also type MAPPOLYUPD on the command line.
2. Select the objects to update. Press Enter

   The topology data for the object is updated in the topology.

If you delete an object from one topology, and the object belongs to another topology, the physical object is not removed from the drawing. The second topology is not changed and no update is necessary for the deleted object.
