Cutting a part of an object

I’m just struggling to cut a part of an object. It’s probably quite simple, but I can’t find a solution right now. :see_no_evil:

I just want to cut off the corner marked by the three lines.
Any ideas?

Can also use sweep + subtract

Ooh… sure! How could I miss it? :smiley:
