Remove one-fourth of a cube

Dear All,

I want to remove 1/4th of a cube. For example, if my cube is of dimension [s,s,s], I want to remove the cuboid of dimension- [s/2, s, s/2]. What is the way to do this? I am able to use the clip function to get 1/4th of the cube. But I want the rest i.e 3/4th of the cube.

Use the same procedure you use to get the 1/4th but uncheck the Invert option when you are applying the Clip filter.
