I noticed this when I saw this odd notch on a cut I just made -
I investigated, and it looks like SW is trying to keep the cut straight through the part, even though I am cutting it at an angle. It is pasting the profile of the cut on both sides of the sheet-metal, and using both profiles to cut the part.
Is this some sort of setting I am unaware of? I'm in SW2016, and attaching the part to this post.
