How it works
The planner sorts cuts longest first and places each into the tightest available gap. When it needs a new board, it chooses the shortest remaining stock length that fits. This is a bounded best-fit heuristic, not a guarantee of the fewest boards or least waste. It uses only the quantities of stock you enter. A full kerf is allowed after each cut except when a piece exactly consumes the remaining board.
The formulaUsed stock = finished pieces + saw kerf + remaining offcuts
Material not in pieces (%) = (kerf + offcuts) ÷ used stock × 100
Good to know
Can I follow the diagram as a guaranteed cut order?
No. Verify dimensions, kerf and a practical cutting sequence yourself. Allow separately for end trimming, defects, grain direction, clamping and blade setup. This tool is for straight length allocation, not structural design or saw-operation instructions.
Why are some cuts unplaced?
Your entered stock may be insufficient, or the heuristic may not find a better arrangement. Unplaced pieces are listed explicitly. Add stock or revise the cut list; do not treat a partial layout as a complete plan.
What are the limits?
Up to 100 lines in each list, 200 stock pieces and 500 required cuts. All stock should have a compatible width, thickness and material for your project. Unused whole boards are reported separately from offcuts.
