■ You can base topology property queries on polygon values of Area, Length,
Perimeter, and Direction. Linear objects also have predefined object data
for Direct Resistance and Direction.
■ Property alterations work differently with polygon topologies.
■ For Report mode, additional dot variables, .TOPONAME, and .TOPOTYPE,
are available for topology queries. The dot variables .DRAWING, AREA,
and .PERIMETER yield different results in topology queries.
Topology Query Result dialog box
NOTE This functionality applies only to drawing objects.
Use this dialog box to specify the type of topology to create with the queried
objects. If you create a temporary or permanent topology, specify a name and
description for the topology.
To query a topology (page 1353)
Click Create tab ➤ Topology panel ➤ Define Query.
Topology names can contain letters, numbers, and the underscore and hyphen
characters. For temporary topologies, the name must begin with an asterisk
(*).
None
Objects are retrieved into the current drawing, but no topology data is
created.
Temporary
Objects are retrieved into the current drawing, and the topology data is
loaded into memory. This data is not saved to the objects.
You can use a temporary topology with the following commands: Buffer,
Dissolve, Overlay, Trace, Unload, Rename, Statistics, and Delete. You cannot
edit a temporary topology.
As soon as you close the current drawing, the temporary topology is removed
from memory.
