NOTE This procedure is for drawing objects only. There is no equivalent for
geospatial feature data.
To edit the direction of a link
1 Verify that the network topology containing the link is loaded. You can
specify link direction for network topologies only.
2 In the map, double-click the link.
If more than one topology contains the same link, select one of the
topologies.
Update the other topologies (page 891) later.
3 In the Properties palette, under the Topo properties, choose a setting for
the Flow Direction property:
■ Bi-Directional — Movement is allowed in both directions.
■ Forward — Movement is allowed only in the direction that the link
was created.
■ Reverse — Movement is allowed only in the opposite direction of the
direction that the link was created.
The new direction setting is assigned to the link.
NOTE You can also store a direction value in an object data table or an external
database table. When you run a shortest path trace, best route analysis, or flood
trace, you can specify the location of this data. When storing this data, use 0 for
Bi-Directional, 1 for Forward, and -1 for Reverse.
