How to create this square bevel/curved effect Just wondering if anyone can advise the best way to achieve this curved effect at the end of a cube.



I tried this tutorial
https://www.youtube.com/watch?v=Y8u66AuY9cA however, what I found was that the faces of the cube then get curved this is not what I am looking for. I tried the bevel effect and again this does not happen to get the desired results.

Will this be a case of adding loop and editing until it looks somewhat like it should, or is there an easier what to get the result I am looking for ?
It looks like the intersection of a cube and a sphere. You can get it easily with a boolean modifier :
