About Cutting Mesh Elements
You can use the Mesh Cut command to slice a shape by mesh elements or a datum plane. You can also use this command to rip a shape along an open chain of edges.
When you slice a shape, the control mesh of a shape divides to form the control mesh of the sliced shapes. After slicing, the sliced shapes replace the original shape. The sliced shapes retain the alignment properties. However, they may lose the existing multi-level mesh changes.
When you rip a shape, the control mesh is cut along an open chain without splitting the shape.
You can select one of the following mesh elements to slice or rip a shape:
• One or more loops of edges
• A set of connected edges with two boundary vertices
• One or more faces
• One or more loops of faces
• Datum plane
• One or more edges forming an open chain
To slice shapes using the plane, you must select a plane that intersects the shapes.
