Use Split to divide faces on a surface or solid, or divide a solid into two components. To start, create a work plane, surface, or sketch geometry to use as the splitting tool. Sketch geometry is projected onto the target faces.
The Split command has two options:
Divides one or more faces to add draft, delete an area to create a surface, and to create new features.
Divides the solid, and creates a component with one portion of the solid.
You can create two components from one solid, or remove a portion of a solid by deleting the new component.
You can split a solid, surface, or quilt.
