If you use a location query to retrieve polygons, make sure that you use a
Crossing window. If you are using data that is shared with other users, be sure
that you load the topology to ensure that you are using current data.
Completing a Topology
When you complete a topology, AutoCAD Map 3D looks at the objects and
object data in a drawing, and attempts to complete a network or polygon
topology by retrieving further drawing objects, such as links and centroids
referenced by the topology object data tables. Complex polygons, with one
or more islands, must be fully represented, and all internal islands referenced
by a polygon must be present for the option to work.
This option completes dangling edges in a network topology, and all
incomplete areas in polygon topologies; however, it might fill islands as well.
Auditing and Recreating a Topology
When you audit a topology, AutoCAD Map 3D checks that a topology is
complete and contains no errors. Any errors found are marked but are not
fixed. Errors in a node topology are not marked.
To reestablish a topology that was edited with nontopology editing commands
such as STRETCH and PEDIT, you recreate the topology; however, topology
data might be lost. You can only recreate a topology in the current drawing;
to recreate topology in an attached drawing, use a query to retrieve the
geometry first. Load the topology before using recreate.
To modify the geometry of a topology (the nodes, links, or polygons), use the
topology editing tools explained in
Editing Topologies (page 851).
