After using the trim function in the way seen below I keep getting faces where I don’t want them and I am missing some faces where I do want them (sometimes). It seems like every other time I get the faces but I end up with a situation like picture 2. I have been working on this for a while but I haven’t had much success. My model units are in mm but I am using the default inches and planning on scaling it back down later.
