A business leftover is a free piece of a sheet that is left after the order parts have been laid out on it. If it is large enough, it is not written off as waste but kept to be put to use. The firm's leftovers are the business leftovers that stay with the firm.
The minimum size of a business leftover
A piece of a sheet becomes a business leftover only if it passes every threshold that is set. There are three thresholds:
- minimum along X — the size of the piece along the X axis of the sheet, mm;
- minimum along Y — the size of the piece along the Y axis of the sheet, mm;
- minimum area — the area of the piece, m².
Sizes are compared strictly along the axes, without rotating the piece: a long side does not “cover” the threshold of the other axis. If only one size threshold is set, it is enough for at least one side to meet it. The area is checked separately and always. The exception is a material explicitly marked in the catalogue as non-textured: such a piece can be rotated, so the thresholds are compared with its shorter and longer sides (see below).
Where the thresholds are set
- For the whole firm — in the admin panel, section “Firm parameters”, folder “Cutting”: “Minimum leftover size along X”, “Minimum leftover size along Y” and “Business leftover area”.
- For a particular material — in the product card, table “Cutting”: fields “Minimum leftover along X” and “Minimum leftover along Y”. When they are filled in, they take priority over the general firm settings for this material. The area threshold is set only for the firm as a whole.
An axis threshold cannot exceed the working area of the sheet (the sheet size minus trimming). If a larger value is set, the system lowers the threshold to the working area by itself — otherwise there would be no business leftovers at all.
How it shows on the cutting map
A piece that fails at least one threshold is treated as waste and does not go into leftovers. On the map such a piece is labelled with the reason — for example, “failed along Y” or “failed by area”. In the totals under the map, each material gets the line “A piece counts as a business leftover: …” with the thresholds in force and a note on where they come from — the material settings or the firm parameters.
When a leftover belongs to the firm
Who owns a business leftover depends on how the material is sold:
- if the material is counted by area — the business leftover always stays with the firm;
- if the material is sold by whole sheets — the leftover of the sheet stays with the firm until it is marked as a client's leftover.
On the cutting map such a leftover shows a «Sale type» switch — it sets how the material is counted and who gets the leftover.
What happens to a firm leftover
The firm's business leftovers are accounted for per order and posted to the leftovers stock. After that they can be used again — as a starting sheet in the next cuttings, saving whole sheets of material.

A textureless material: the leftover is measured in any orientation
The minimum sizes of a reusable leftover are set per axis: a minimum along X and a minimum along Y. When the catalogue explicitly marks a material as textureless, the sheet may be laid either way round, so the thresholds are measured against the shorter and the longer side of the piece instead of strictly along the axes.
For example, with the minimums X = 550 and Y = 450 the pieces 550×450 and 450×550 are both reusable for a textureless material. For a textured one the second piece does not become a leftover: it cannot be rotated.
The rule works only on the explicit flag. If the texture flag has not been set on the material, the previous order applies — strictly along the axes.
