Setting the target LRS Network layer

All changes to LRS Networks must be made using the Roads And Highways Editing toolbar. They cannot be edited in ArcMap using conventional editing tools. Attempting to edit the network features directly introduces a substantial risk of corrupting your data. Tools on the Roads And Highways Editing toolbar synchronize the centerline feature class, the centerline sequence table, the route table, and calibration points to ensure proper construction and calibration of LRS Networks.

LRS Networks are selected using the Networks drop-down menu on the Roads And Highways Editing toolbar. You must be in an edit session for the Roads and Highways Editing toolbar to be active.

Steps:

1. Start ArcMap and add the LRS network and centerline feature classes to your map.
2. Start an edit session.
3. Click the Networks drop-down arrow to choose an LRS Network to edit.

The network remains selected in the Networks drop-down menu when performing tasks such as create, extend, realign, reassign, or retire routes.

Note:

The Networks drop-down list may reset if a new data source is selected for editing or the network is no longer in the MXD.
