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 equal zero, every
possible route is as good as any other route, and there is no "best" route to travel.

To perform a best route analysis
1 Verify that you have a network topology available and it is loaded. See
Creating Topologies (page 821) and To load a topology (page 907).
2 In
Map Explorer (page 2068) under Current Drawing, right-click a network
topology ➤ Analysis ➤ Network Analysis.
3 In the
Network Topology Analysis - Select Method dialog box (page 1983),
click Best Route. Click Next.
4 In the Network Topology Analysis - Choose Locations dialog box, click
Start Point. Click Select Point
to select the starting point in the
drawing. Press Enter to return to the dialog box.
AutoCAD Map 3D uses the node closest to the location you clicked as
the start point. The coordinates of the point are shown in the list.
5 Click Visit Point. Click
(Select Point).
6 In the drawing, click a point to visit during the best route analysis. It
does not matter which point you pick first, AutoCAD Map 3D calculates
the order in which to visit the sites as part of the calculation.
AutoCAD Map 3D uses the node closest to the location you clicked as
the visit point.
7 Do one of the following:
■ To accept the point and return to the dialog box, press Enter.
