Install

Edit > Preferences > Get Extensions > Install from Disk (the arrow menu at the top right), then pick the .zip. Do not unzip it. Requires Blender 4.2 or newer.

Use

1. Open the sidebar in the 3D Viewport (N) and the Cut List tab.
2. Pick the parts (Selected, Visible or a Collection) and the unit.
3. Press Make Cut List. Read it in the panel or in the Text Editor ("Cut List").
4. Press Export CSV for Excel, Google Sheets or a panel-cutting optimizer. Choose comma + decimal point (US/UK) or semicolon + decimal comma (European and Brazilian Excel).

Notes

The size shown is the blank to cut. Curves, text and other non-mesh objects are skipped; convert them to mesh first. Boards that share vertices inside one object count as one piece.
