Dissolving Network Links
When you dissolve a network topology, AutoCAD Map 3D checks nodes
between lines to see whether two lines intersect at a specified node and whether
the dissolve field is the same. If so, the node is removed, and the two links
are joined to form one link. All object fields except for the dissolve and any
new topology fields are removed as shown in the following illustration.
If adjacent lines do not contain the dissolve field, the node is not dissolved
and the resulting polyline has a blank value for that field.

To dissolve a composite topology
1 In
Map Explorer (page 2068), right-click the topology to dissolve ➤ Analysis
➤ Dissolve.
2 Note that topologies must be loaded before you can work with them. See
To load a topology (page 907).
3 In the
Topology Dissolve - Set Parameter dialog box (page 1998), for Dissolve
By, specify the data element to use for the new topology. To select a field
from an object data table or a column from an external database, click
(Expression Evaluator).
