Every bar and every sheet, drawn to scale
See which pieces come off which stock length, in what order, and where the offcut falls.
Free 1D and 2D cutting optimizer
Optimize your cutting. Minimize your waste.
ScrapZero works out how to cut stock pipes, bars and sheets into the parts you need with the least waste, and draws the plan bar by bar and sheet by sheet.
Linear cutting for pipes, tubes and profiles, nesting for rectangular sheet parts, waste figures for every plan, and a PDF for the shop floor.

The order you cut in decides how much you throw away
Cutting pieces off a bar in the order they appear on the list leaves short offcuts nobody can use. Choosing which pieces share a bar is a combinatorial problem, and that is the part ScrapZero solves.
Cut in list order
3 bars · 6,600 mm left overEach piece goes on the first bar it fits. The offcuts are too short to use, and a third bar is opened for a single piece.
Cut to an optimized pattern
2 bars · 600 mm left overThe same six pieces, combined so each bar is nearly full. One whole bar stays on the rack.
Worked example: two each of 2400, 1800 and 1500 mm from 6000 mm bars, blade width ignored.
A plan you can cut from, not just a number
Every result is drawn to scale, totalled and ready to print.
