Feature Description

The intersect operation obtains the common parts of two or multiple objects. Through this operation, you can create new objects by processing the overlapping areas of two or more objects with the same geometry type. The common areas of multiple objects will be preserved while other parts will be removed. Note that intersect operations are not supported between lines.

• If the pairwise intersections of participating polygon objects are non-empty, simple objects will be created from the overlapping areas after the operation.

  Before Intersect	After Intersect

• If the pairwise intersections of participating polygon objects are empty, all source objects will be deleted without generating new objects.

  As shown above, when pairwise intersections of participating polygons are empty, source objects will be deleted after the operation.

• Attribute description for newly created objects. Use the attribute dialog to specify which object's attributes to retain and how to process field values. For details about the Property Processing dialog parameters, see Property Processing Dialog Description.
• In CAD layers, the operation results of polygon objects, rectangles, circles, or oblique ellipse objects will generate new polygon objects.
• Cross-layer intersect. Selected objects from other layers will perform intersect operations with objects in the current editable layer. Only objects in the current editable layer will be modified. For multi-layer editing, intersect operations are only performed on specified editable layers.

Feature Entry

• Features Tab->Feature Editing Group->Intersect。

Steps

1. Ensure layer is editable and select two or multiple objects.
2. In the Features tab's Feature Editing group Gallery control, click the Intersect button in the Object Operation group to open the Intersect dialog.
3. Set the objects to retain in the dialog. For parameter descriptions, refer to Property Processing Dialog Description.
