I have a weird thing going on. I am trying to use Normal Cut feature to normalize a beveled cut in a sheet metal part - but for some reason, instead of removing extra material like it normally does, in this part it adds some:
Why does it work like this, and how do I make it remove material instead of add it? I know there are other ways to make this cut, but I need this specific feature because there will be a lot of similar cuts, and Normal Cut is the most convenient feature for this, by far.
Attaching the file.
