@Chopsaw I'm playing around with this. It seems a bit tricky to do it in just one spot (more as framing than a surface layer), but it seems plausible.
Some of these structural elements may simply be better left as notes or up to interpretation of the framers...
EDIT: Okay I just stumbled onto something w/respect to roof overframing! In some instances you may need two enable overframing on _both_ the "under" _and_ the "over" planes. When I first tested out the feature I only needed to do it for the "under", but just on a whim I tried doing it on the over and all of a sudden the shoe plate appeared!
In the photo below, both planes 1 & 2 have overframing enabled.
