Fourteen structures, each with its own number.

Every card below carries the style's real dieline — drawn by the shipping engine at one of its reference die sizes, not illustrated — its FEFCO or vendor model code where one exists, the worst deviation we measured against the reference dies, and how many dies that figure rests on. Selecting a card opens that structure in the studio.

Grouped by confidence, best first. 62 vendor production dies behind thirteen of the fourteen. The fourteenth has none, and says so on its card.

Verified — 0.25 mm or better10 styles

Solved against real vendor production dies and re-measurable on demand. The published figure is the worst point found across every sampled size on every path — not an average. It applies inside the range those dies sampled; outside it the studio reports Extrapolating and stops claiming.

Grocery Paper Bag (SOS) · 381 × 127 × 254 mm pbgVerified Grocery Paper Bag (SOS) Model 220013 Best in the set. The sheet-width law is exact on all four dies.

Verified, wider tolerance3 styles

Usable with a proof, not without one. Each of these was solved against real dies, and each has a specific, named reason for sitting outside 0.25 mm. Two of the three moved in the August 2026 patch, and the direction of the move is printed on the card.

Reverse Tuck End · 120 × 60 × 160 mm rteWider tolerance Reverse Tuck End Model 100010 Was 10.87 mm before the August 2026 patch. Squat boxes (H ≤ W) are not die-evidenced.

Draft — not production ready1 style

No die behind it at any size. This structure is composed from two separately verified modules and has never been checked as a whole, so there is no deviation to publish — not a good one and not a bad one. It is in the product because it is useful for laying out a concept. Do not send it to plate.

123-Bottom Tuck Top · 120 × 60 × 160 mm tcbDraft 123-Bottom Tuck Top No FEFCO or model code on record Never derived from a die. Composed from the verified RTE tube and the verified GBH 1-2-3 bottom. Do not send it to plate. Worst deviation— Reference dies0 Open in the studio

About the drawings on these cards

Each thumbnail is the actual generator output for that style, run at one of the sizes its reference dies were measured at, then rescaled. Two things are simplified at this size and nowhere else: the bleed layer is omitted, and collinear vertices closer than 0.3 units after scaling are dropped so the page stays small. Cut and crease are the engine's own geometry at production colours — #FF0000 and #0000FF. Nothing here is drawn by hand.

Dimensions shown on each drawing's tooltip are the reference size, in millimetres. In the studio every one of them is adjustable, and the validity envelope will tell you the moment you leave the range the dies sampled.
