About this 2-CSP glass and panel nester

This public tool is a browser 2-CSP solver for window shops: insulating glass units, infill panels and rectangular sheets. Plywood, lumber and fabric rolls are not the primary audience.

Worked example

One 3210 × 2250 mm sheet, ten 1160 × 1400 mm IGUs, kerf 5 mm. Enter the sheet as stock and the IGU as a required panel; calculate to see how many sheets the nest needs and what leftover remains. For a single identical size on one sheet, use the piece count calculator.

Import stocks and panels from one CSV or Excel file — see the import manual — or copy the cells in Excel or Google Sheets and use Paste table (free, log in required). Same 1D/2D cutlist class as a generic optimizer, different shop: compare FeneCAM vs Opticutter. Export PDF, XLS, CSV or DXF. Free limits: 5 stock sizes · 20 panel sizes · 500 panels.
