Flagship cut planning tool

Cut optimizer with stock planning, waste, cost, and printable cut sheet

Build a practical cut list for plywood, panels, boards, or trim, then review used stock, waste, warnings, labels, CSV rows, and a print-ready planning report.

Examples

Project

Setup

Mode, kerf, and buffer

Stock dimensions and price drive the purchase list. Sheet mode needs width.

Cut rules
Stock

Stock sizes

Stock dimensions and price drive the purchase list. Sheet mode needs width.

Parts

Part list

Add parts with positive dimensions and quantity; the optimizer sorts the list for placement.

Why planners use it

  • Keeps stock sizes, part rows, kerf, rotation, and overage in one connected workspace.
  • Shows a visual layout preview plus a report packet you can print or copy before shop work.
  • Saves drafts only in the current browser so sensitive project dimensions do not need a backend.

What to review before ordering

  • The cut optimizer is a deterministic planning helper. Verify grain direction, defects, clamps, trim allowance, and saw setup before cutting.
  • Kerf and overage are included in the planning math, but real shops should still review the printed list before ordering stock.

How the cut optimizer handles the plan

The optimizer expands each quantity into individual parts, sorts larger pieces first, then places them into available stock while accounting for kerf and the selected stock mode.

The visual layout is a planning preview. Always check real sheet defects, grain, clamp clearance, trim allowance, and shop sequencing before cutting.

Frequently asked questions

Can I use sheet and linear stock?

Yes. Switch between sheet, board, and linear modes. Sheet mode uses width and length, while board and linear modes use stock length.

Does grain lock prevent rotation?

Yes. When grain lock is enabled, sheet parts stay in their entered orientation even if rotation is otherwise allowed.

Can I save cut plans?

Yes. Drafts are saved only in the current browser and can be loaded, duplicated, deleted, exported to CSV, copied, or printed.
