route between two points by entering the expression (/ .length (*
:speed@street_data 5280) which divides the length of each link by the
average speed per foot (where 5280 is the number of feet in a mile).
NOTE The best route cannot be calculated if the network topology contains
negative resistance values or if all resistance values equal "0" (or use
expressions that evaluate to zero). In layman's terms, if all resistance values
are all zero, every possible route is as good as any other route, and there is
no "best" route to travel.

12 In the Network Topology Analysis - Output dialog box, indicate whether
or not to view the results of the trace onscreen and whether to save the
trace results as a new topology.
■ To view the best route analysis onscreen, select Highlight and choose
a highlight color.
Use a highlight color that is different from the color of the objects in
your map.
■ To save the results of the best route analysis as a new topology, select
Create Topology and enter a name and description for the new
topology.
AutoCAD Map 3D adds topology information, stored as object data,
on each element that makes up the best route topology.
13 Click Finish to perform the best route analysis.
To display the order in which to visit points, use annotation to label the
best route with the object data stored on the best route topology objects.
For more information, see
To insert annotation (page 1103).
