Clipping features and preserving features that fall within the clip geometry

The Cut Features tool allows you to perform Discard Clip, Preserve Clip, or Split operations based on the feature classes you have selected within your data frame. The features you select are considered the cut features, and their geometry is used to perform the chosen operation on the target features. Target features are any features in the target layers that have a spatial relationship with the cut feature. These feature classes are updated during the selected operation. You can also choose which target features are affected by the operation you select.

The Cut Features tool splits the target features at the boundary of the selected cut feature and deletes the portions of the split target features that fall outside the boundary of the cut feature. Only polygon features can be used as the cut features.

Only polygon and line features from the target layers that touch or overlap a boundary of the cut feature are removed. Other features in the target layers are not removed or modified.

Étapes :

1. Start ArcMap.
   Conseil :

   If the ArcMap - Getting Started dialog box appears, you can open a new or existing map document. You can also check the Do not show this dialog box in the future check box and click Open.

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 on the Production Editing toolbar.
   Remarque :

   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.

   Conseil :

   If the Create Attributes, Update Attributes, or Metadata Attributes window does not appear when you start an edit session, click the Link Feature Manager To Attributes Window button on the Manage Features window.

5. Select the features you want to use for your cut features.
6. Click the Cut Features button on the Production Editing Advanced toolbar.

   The Cut Features dialog box appears. All features that intersect, contain, or are contained within the selected cut features are included on the Layers and Schema tabs in the Target area.

7. Choose Preserve Clip in the Operation area.
   Remarque :

   The Union cut features check box is unavailable with this operation because it can be used only when lines, not polygons, are selected.

8. On the list in the Target area, check the check boxes next to the target layers to be affected by the operation.
9. If you want to choose the exact subtypes for use with the Cut Features tool, check the Show Subtypes check box and check the check boxes next to the subtypes to be affected.
10. If you do not want to keep the features that are coincident with the cut geometry, uncheck the Keep coincident parts check box.
11. If you do not want features outside the current extent to be removed, check the Only modify features within the current extent check box.

    When the Only modify features within the current extent check box is checked, features that are completely within the current extent or overlap the current extent are affected by the Cut Features tool.

12. If you are using z-enabled features, choose an option in the Z Values area.
    • Use Feature Geometry—This method uses the z-values from the feature that is split or clipped. Where the feature has been clipped, the vertex has a z-value that is interpolated from the original z-values defined for the vertices on the feature. For instance, if a line feature is split in the middle, the vertex on the clipped ends would have a z-value that is an interpolation of the split feature's original z-values. If the two z-values are 10 and 20, the z-values at the clipped ends would be 15.
    • Use Clip Geometry—This method uses the z-values from the selected cut feature. Where the feature is clipped, the vertex inherits the selected cut feature's z-value. For example, if a polygon is clipped, and the cut feature has z-values of 50 for all its vertices, the vertices created on the feature that is split or clipped are going to have a z-value of 50.
13. Click Apply.
14. Click Close to close the Cut Features dialog box.
