Specifying the Resistance for a Link or Node
Concept Procedure Quick Reference
 
 
 

Direct Resistance is the resistance to travel in the direction that a link was created, while Reverse Resistance is the resistance in the opposite direction along a link.

For both types, you can specify a resistance for any link in the network topology. This resistance specifies the difficulty in traversing the link. The default resistance is the length of the link.

AutoCAD Map 3D uses this resistance when doing a shortest path trace, best route analysis, or flood trace. For an example of using resistance to show travel times, see Performing a Flood Trace.

You can also specify the Resistance of a node in a network topology, such as setting resistance for a valve in a pipe network, or a junction in a road network.
