Splitting line features

This topic applies to ArcEditor and ArcInfo only.

The Split tool splits a single existing polyline feature into two at a specified location. This is similar to the Create and Intersect Features construction tool, which you can use to create new features by intersecting and dividing preexisting features. The difference is that the Split tool only splits an existing line feature at a single point, while the construction tool can be used to create several features at once.

Example of a feature split at a specified location
A line that has been split into two separate features

When the line is split, one of the features keeps the original attributes of the line feature, such as the ObjectID and GFID. The new feature retains the same subtype and related information as the original feature, as appropriate, but has a different ObjectID and GFID.

  1. Start ArcMap.
  2. If necessary, load data in the map.
  3. On the main menu, click Customize > Toolbars > Production Editing.
  4. Click the Production Start Editing button Production Start Editing on the Production Editing toolbar.

    The Manage Features and Create Attributes, Update Attributes, or Metadata Attributes windows automatically appear when you start an edit session using the Production Start Editing tool.


    If the Create Attributes, Update Attributes, or Metadata Attributes window does not appear when you start an edit session, click the Show/Hide Attributes button Show/Hide Attributes on the Manage Features window.

  5. Select a polyline feature to split.
  6. Click the Split tool Split on the Production Editing toolbar.
  7. Click the feature at the location where you want to split the polyline.

The line is split at the designated location.
