Querying a Topology
Use a topology query to retrieve a loaded topology and its associated data
from the current drawing or an attached drawing. You can also query part of
a topology in a source drawing and work on that part of a topology without
having to retrieve all the objects that make up a topology.
NOTE This functionality applies only to drawing objects. There is no equivalent
for geospatial feature data.
There are three differences between using standard queries and topology
queries:
■ Topology queries work with only one topology; standard queries work
with all objects in the attached drawings.
■ Because topology information is stored in object data, a Data condition
can be based on Area, Length, Perimeter, Direction, Direct Resistance, and
Reverse Resistance.
■ Property alterations work differently with polygon topologies.
