TradeA room total helps check quantity. A stock plan needs the length of every piece. Enter each uninterrupted finished blank separately, label it by wall or room, and confirm its length before purchasing.
Why a perimeter total is not a cut list
Two 1,200 mm pieces and one 2,400 mm piece have the same total length. They do not fit the same stock when saw loss is included. Subtracting a doorway from the room perimeter also does not establish the lengths on either side of that doorway.
A small stock check
Two confirmed 1,000 mm blanks, a 3 mm kerf, and 5 mm of preparation allowance at each end consume 2,016 mm. A 2,400 mm board leaves 384 mm of offcut. The other 16 mm is saw and preparation loss.
TradeLedge budgets one kerf per extracted piece, including the last piece. It never splits a long piece to make it fit. Keep different profiles in separate groups and enter the supplier's actual stock lengths and prices.
