Using Clip Path
Clip Path is used to mark out certain region of a shape.
Clipper (must be a single shape) is a shape that is on top of another while Clippy (can be multiple shapes but grouped) is a shape that lies behind the clipper.
Only the region that is bounded by the Clipper of the Clippy can be seen after clipping.
Note: A clipper can be any basic shapes, but it cannot be a grouped shape.
