You can add a new or
existing link to a network or polygon topology. The current drawing
must be where the topology was created.
Create new links between
existing nodes. Add
nodes as needed. New links cannot cross
other links. If you draw a line or arc, it is converted to a polyline.
When adding links to
polygon topologies, AutoCAD Map 3D updates the centroid, the area, and
perimeter values of the polygons. You can also divide a polygon
using the MAPDVP command.
You cannot add links
to node topologies.
