Formulas used
Sheet Area = SheetWidth × SheetHeightPiece Area = Width × HeightTotal Pieces Area = Σ Piece Area × QuantityWaste % = (1 − TotalPiecesArea ÷ (Sheets × SheetArea)) × 100- Kerf is applied as spacing between adjacent cuts and shelf rows.
Placement uses a shelf heuristic: parts fill rows across, starting new shelves when needed; new sheets are created when height is exceeded.
How to use
- Choose units, sheet size, kerf, and edge margin.
- Add parts with quantities and dimensions; tick no-rotate to lock grain.
- Click Calculate layout to generate sheet maps.
- Review waste and part placement; tweak inputs if needed.
- Export CSV for cut lists or PDF for printing.
