Instead of only cutting what I've selected for it to cut, it cuts everything except for what I've told it not to cut. This is very time consuming trying to draw all sorts of avoidance boundaries. I really don't understand why it's like this. I'm only on 2018 and I don't see this shop updating in the foreseeable future - so maybe this is something that has been fixed in subsequent releases? But if it isn't, it really should be.
