ArcGIS Pro: Split failed. Geometry must intersect polylines and polygons in two or more places

Error Message

When attempting to run the Split tool, the process fails and returns the following error:

Error:
Split failed. Geometry must intersect polylines and polygons in two or more places.

Cause

• The features are not properly connected.
• The feature class has invalid geometry or complex geometry.
• The feature class is corrupted or broken.

Solution or Workaround

Depending on the cause, the workarounds provided are applicable.

Connect the vertices using the Edit Vertices tool

To split features using the Split tool, the vertices of the features must be properly connected. Use the Edit Vertices tool to connect the vertices between the features. Refer to ArcGIS Pro: Move a vertex for instructions.

Repair the broken geometries using the Repair Geometry tool

1. Open the ArcGIS Pro project.
2. Navigate to the Analysis tab and click Tools.
3. In the Geoprocessing pane, search for and select Repair Geometry (Data Management Tools).
4. Configure the parameters in the Repair Geometry pane.
   1. For Input Features, select the feature layer from the drop-down menu. In this example, the layer selected is LineAK1.
   2. Optionally, check the Delete Features with Null Geometry check box.

Note:
Checking the Delete Features with Null Geometry check box deletes features with null geometry from the input. This is the default.

3. For Validation Method, specify the geometry validation method. In this example, the geometry validation method is Esri.
4. Optionally, toggle Enable Undo on.

Note:
Toggling Enable Undo on reverses the changes applied by the tool.

5. Click Run.

Export the features to a new feature class using the Export Features tool

Note:
The Export Features tool has replaced the Feature Class To Feature Class tool in ArcGIS Pro 3.2 and above.

1. Open the ArcGIS Pro project.
2. On the top ribbon, navigate to the Analysis tab and click Tools.
3. In the Geoprocessing pane, search for and select Export Features (Conversion Tools).
4. Configure the parameters in the Export Features pane.
   1. For Input Features, select the feature layer from the drop-down menu. In this example, LineAK1 is selected.
   2. For Output Feature Class, click Browse and specify the location for the output feature class.
   3. Click OK.

Note:
Alternatively, in the Content pane, right-click the feature layer and click Data > Export Features.
