Performing a Shortest Path Trace
Using a network topology, which is made up of drawing objects and their
relationship data, you can calculate the shortest path between two points in
a drawing or determine the optimal route based on values of resistance and
direction. This process is known as a shortest path trace analysis.
In a drawing of a street network, for example, you might find the shortest
path between a fire station and a school.
Shortest path trace based on resistance (time taken to traverse a segment).
You can specify a resistance for any link in the network. This resistance specifies
the difficulty in traversing the link. The default resistance is the length of the
link.
If a path has a total resistance lower than the Minimum Resistance value, the
path is ignored. Similarly, if a path has a total resistance greater than the
Maximum Resistance value, the path is ignored.
