The plan that goes to the table
The optimiser tells you how many sheets. This is the piece of paper the cutter works from. A labelled diagram for every sheet, the cuts in the order they are made with the measurement for each one, every offcut with its real size so it can go back on the rack under a label, and the material and cost at the top.
This is the document it prints
One page per sheet: the diagram with every pane labelled, then the cuts in the order the table makes them — across for the strip, along for the column, across for the pane. The same codes are on the labels.
Sheet 1 3210 × 2250 · 6 mm clear
| Cut | What it frees |
|---|---|
| Trim 10 mm off all four edges | leaves 3190 × 2230 of usable glass |
| Strip 1 — cut across at Y = 860 mm | frees a band 3190 × 850 mm (from Y = 10). Work on this strip before cutting the next one. |
| Rip at X = 1210 mm | column 1 of strip 1, 1200 mm wide (allow 3 mm breakout) |
| Last piece of the column → A1 | 1200 × 850 mm |
| Rip at X = 2410 mm | column 2 of strip 1, 1200 mm wide (allow 3 mm breakout) |
| Last piece of the column → A2 | 1200 × 850 mm |
…and on down the sheet. The real plan runs to the last pane and lists every offcut with the size to write on it.
Nothing to print yet
The plan is made from a nest the optimiser has already solved, so there has to be one first. Lay a cutting list out there and the button on that page brings you straight back here with the job loaded.
Nest a cutting list →What is on the sheet, and why
The diagram. One per sheet, to scale, with every piece carrying a label rather than only a size. A cutter holding twelve identical 1050 × 850 lights needs to be able to say A7; a list of sizes cannot tell them which one came off where, and the labels are what make the offcut list and the cut order refer to the same objects.
The cut order. Three-stage guillotine, in the order the table performs it: the edge trim, then each full-width strip, then the rips that divide a strip into columns, then the crosscuts that take the pieces off a column. Every line carries the measurement from the same corner used in the diagram — top-left, X across, Y down. That is the only thing on the page that has to be unambiguous, so it is stated on the print as well as here.
The offcut list. Not one figure for waste, but each surviving rectangle with its real width and height and where it came from. Three shapes come out of a three-stage nest: the band above the last strip, what is left at the end of a strip, and what is left above the last piece in a column. All three are glass you can rack and use; the number at the top of most optimisers quietly counts them as waste. Anything below the size you set — 150 mm by default — is treated as scrap instead, because nobody racks a sliver.
The cost. Scrap only, at the price you entered. The glass that goes back on the rack is not a loss, and calling it one is how software makes its own results look worse than they are.
