Trying to add some detail to a gable wall by extending it over a custom bay window structure. Ceiling on 2nd floor is ok, and the framing appears to be decent, but I just can't get the underside of the cantilever/boxing to cover. I've tried many tutorials on cantilevers, but it doesn't seem to apply to this scenario when automating the build. Is this possible, or do I just need to manually create the area? This current version was accomplished by creating a 3rd floor, and adding a new gable end wall. I also increased the overhang length. Thank you.
