Bay windows, balconies and bumped-out rooms all hang floor joists past a support. The floor layout in Wall Framing Takeoff could not model that, so builders had to fudge the depth. It now takes floor.cantilever (inches, up to 8 ft).
The joists, rim board and subfloor courses run the extra length. A 28 ft supported span with a 2 ft overhang frames 30 ft, and the subfloor splits into seven full 4 ft courses and a 2 ft strip. The tests count those figures by hand.
The tool does not size the overhang. It adds a note when the cantilever is more than a third of the supported span, against the common 3-to-1 backspan rule of thumb, and says the engineer has to check it. The page has no field for it yet; use the plan file or the CLI.
