Splitting Polylines at Nodes

A single-section polyline can be split into two polylines at a selected node.

To split a single-section polyline:

1. From an editable layer, select a single-section polyline
2. On the SPATIAL tab, in the Edit group, click Reshape from the list.
3. Select one node (other than the first or last node).
4. On the SPATIAL tab, in the Edit group, click Split, and Split Target using Polyline.
5. If a layer is not a cosmetic layer, the Data Disaggregation dialog box opens. Here you can specify how data is disaggregated.
6. After selecting the data disaggregation method, click OK.

The selected polyline splits at the node to create two polylines.

Error messages display under the following conditions:

• You did not select a node of the polyline.
• You selected a beginning or ending node of the polyline.
• You selected more than one node of the polyline.
• The object that you selected is not a polyline object.
• You attempted to split a multi-segmented polyline (only single-section polylines can be split).
