Cutting the Corner off a Cube in Fusion 360 is Broken

Fusion 360 is broken.
Cutting the corner off a cube is awkward because you can't delete the corner. Instead you have to create a copy of the cube with the cut off corner, then you can delete the original and the corner.
WHY?????!!!!!!!

Instead of making a copy of the corner. Make that body part(corner) into a component, then right click the component and click remove. thus the corner is deleted without the need to make copy of the corner nor copy of the entire part
