- An existing arc can be split by:
2. Add a node the arc.

3. Add a new connecting arc.
|
- Use the Create Feature Arc tool to start or end a new arc on an existing arc to split the existing arc into two arcs.
|
|
4. Merge arcs.
|
- Two arcs that share an end node can be merged together.
- Select the shared node using the Select Feature Node tool.
- Right-click on the node and select the Convert to Vertex command to merge the arcs.
- If desired, the Select Feature Vertex tool can be used to select and delete the new vertex.
