The wall-framing takeoff already framed decks on its page: joists, beam, posts, footings and decking rows. The guard (railing) was only reachable from the command line. The deck card now has a Guard switch (automatic over 30 in above grade, always, or none) and a Guarded edges choice (all open edges, outer only, or outer plus the two sides).
Driven in Chromium on a 16 by 12 ft deck at 48 in with the outer edge guarded: 4 posts, 33 balusters of 29 in (clear gap at most 3-11/16 in) and 2 rails of 2x4 pressure-treated joining the lumber order.
What is not checked: the arithmetic is hand-computed, post attachment is yours to detail, and your local code sets the guard height and the gap. No real permitted deck plan has been run through it yet; that is what we want next. Deck stairs are still CLI only.
