Creating a new network edge at an existing junction

This topic applies to ArcEditor and ArcInfo only.

Steps:

1. Add your network feature classes to ArcMap.
2. Click the Editor Toolbar button on the Standard toolbar.
3. Click the Editor menu on the Editor toolbar and click Start Editing.
4. Zoom to the area where you want to add the new feature.
5. In the Create Features window, click the type of edge feature you want to create, and click the Line construction tool.
6. Click Customize > Toolbars > Snapping.
7. Activate Point Snapping and deactivate the other snapping options.
8. Move the pointer near the junction to which you want to snap this edge until the pointer snaps to it.
9. Click the map to create the new feature's vertices.
10. Double-click the last vertex to finish the feature.

You have now created a new network edge. Since you snapped it to an existing network junction, it is automatically connected to the network. If there is an edge–junction rule for the new edge with a default end junction type specified, this junction type will be placed at the free end of the new edge. If there is not an edge–junction rule that specifies a default junction, an orphan junction will be placed at the end of the new edge. For information on how to replace the orphan junction with another junction type, see the task Subsuming network junctions.

Tip:

• You can specify what type of junction is placed at the free end of new edges by creating an edge–junction rule. For more information on connectivity rules, see About geometric network connectivity rules.
