Plan offcuts and record the real remnant
SlabOS works out the offcut from the saved slab layout before anything is cut: yield per slab, square feet of offcut for the quote, and saw run-outs that land in leftover stone. At the saw, the shop measures the real offcut and saves it with Create Remnant as its own slab with a -r1 serial, barcode and label, so it can turn up as matching stock on the next quote.

SlabOS — Know the offcut before the cut (SlabOS-Predicted-Remnant-Yield-v2)
All on-screen information, in order. No voice-over. Layout from a real SlabOS Auto Nest run.
What's left after the cut?
Slab 3, 126 by 63 inches, holds one piece: CT3, the island.
The layout sees it first.
Kitchen, Auto Nest. Veined material, the default mode. Three slabs, each 126 by 63 inches: Slab 1 holds CT1.1 and CT1.2, Slab 2 holds CT2, Slab 3 holds CT3.
Estimate, from the layout. Yield per slab: Slab 1 63.2%, Slab 2 23.6%, Slab 3 44.4%.
Saved layouts, 55.13 square-foot slabs. Pieces plus strips divided by slab area, before cutouts.
93.06 square feet of offcut. Yield 43.7% for the whole quote. Step 6, Slab waste (you only).
Estimate, before the cut. Show Cut Lines is switched on: the four saw cuts around the island are drawn, then eight dashed run-outs.
8 into offcut. Saw cuts clear. Run-outs that only scar leftover stone.
Measured, at the saw. Slab 3 is cut: the island goes to the job and the offcut beside it is measured, 63 by 41 inches.
Create Remnant from This Slab: Length (in) 63, Width (in) 41, Also mark the original slab as Consumed (ticked), Create Remnant.
Saved as a new slab: SL-2049-r1. Remnant, Available. Own barcode, linked to SL-2049. A label is printed for it.
Next quote. It comes back.
You have 1 matching slab available in inventory, including 1 remnant. View & use. Same material, color and thickness.

Notes for the page:
- The estimate numbers are the ones SlabOS computes from this saved layout (piece and strip area against slab area). They show total leftover area, not the size of a usable remnant.
- The remnant size is measured by the shop and entered in Create Remnant from This Slab; SlabOS then saves it as its own slab with a -r1 serial, its own barcode and a link to the parent slab.
- None of the features shown carries a BETA label in the product.
Understand the estimate before treating an offcut as reusable stock.
The SlabOS feature list includes predicted remnant yield. For a fabricator, the decision is whether the proposed layout leaves material that is both geometrically useful and operationally worth keeping. That question depends on more than unused area.
The existing operating documentation supplies the surrounding workflow: saved slab layouts, consumption, a separately identified remnant, and yield reporting with coverage and exclusions. The next documentation layer needs to connect the prediction itself to those saved results, including the definition of usable remainder and the assumptions applied to the source slab.
Inputs, outputs and an example to evaluate
Inputs: Individual slabs, dimensions, material identity, location and countertop pieces.
Outputs: Inventory records, planned layouts, stock holds and applicable remnant records.
Follow a sample slab from receipt into a quoted layout and show its subsequent consumption and remnant history.

Current product capabilities
The nesting page connects automatic placement of the drawn pieces to actual inventory slabs and the shop’s price lists. It describes re-nesting when the drawing changes. Yield and runtime comparisons still need a defined test dataset and retained output. Read the Slab Nesting page →
The warehouse page connects buildings, bays and racks with slab inventory, quotes and purchasing context. Per-bay capacity indicators, phone searches and printable floor plans make recorded stock location useful beyond an inventory table. Read the Warehouse Map page →
