Creating a new network edge along a complex edge

Available with Standard or Advanced license.

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 Edge Snapping and deactivate the other snapping options.
8. Move the pointer over the complex edge where you want the edge to snap 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 the edge of an existing edge, if there is an edge–edge connectivity rule between these edges, a new junction is created—the default junction type for that rule. If there is no edge–edge rule, then the new junction is the default network junction. If there is an edge–junction rule for the new edge that has a default end junction type specified, this junction type will be added. If there is no edge–junction connectivity rule, an orphan junction is added. Since the edge that was snapped to is a complex edge, it remains as a single feature but is split in the logical network.

11. Click the Edit tool on the Editor toolbar.
12. Click the complex edge to which you snapped your new edge.

    The entire edge is selected even though another edge and junction are connected along it. It remains a single feature.

Tip:

• You can also snap a junction along a complex edge. Similar to snapping an edge, the junction is connected to the network. The complex edge is split in the logical network but remains a single feature.
• 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.
