This page is for an agent, a pattern maker, a CAD operator, or anyone who needs to confirm a digital marker's own fabric consumption before cutting begins. This lesson mainly teaches the money flow: what a marker's own efficiency actually costs or saves in fabric, at real prices.
Meridian Sourcing, acting for a European buyer, is checking a digital marker Delta Garments built for a hybrid top-up run of 2,000 extra T-shirts on top of Order A's own 15,000-piece Make to Order base, at Order A's own fixed 93% marker efficiency. An agent new to CAD marker-making tends to assume a digital marker automatically reaches its own best possible efficiency. In fact a CAD system only lays pattern pieces out to whatever target and settings a person gives it; someone still has to check the result against the fabric consumption the order can actually afford.
You need: lesson T25-C01-L03 is useful background but not required. A basic idea of what marker efficiency means is enough to start; Order A's own fixed marker and fabric figures are given in full below.
By the end of this lesson you can:
Not covered here: grading a pattern across a size run (lesson T25-C01-L03), and assembling digitizing, grading and marker-building into one complete worksheet (lesson T25-C01-L05).
| Term | Meaning |
|---|---|
| Marker | The layout of all pattern pieces for a size, or a set of sizes, arranged on fabric width, used to cut fabric with the least possible waste. |
| Marker efficiency | The percentage of fabric in a marker actually used for pattern pieces, the standard-industry complement of marker wastage. |
| Marker wastage | Fabric lost during cutting because pattern pieces never fill a cutting layout perfectly; a separate allowance from combing waste. |
| Nested marker | A marker whose pieces are arranged tightly, odd-shaped pieces fitted into each other's gaps, to reduce unused fabric between them. |
| Multi-size marker (ratio marker) | A marker containing pattern pieces for several sizes together, laid out in the order's own size ratio. |
| Target consumption | The fabric quantity per piece, or per order, a marker is expected to achieve before cutting is approved. |
| Marker-planning worksheet | A document that records a pattern's grade rule, a marker's size ratio and layout, and its calculated wastage, efficiency and fabric requirement, so all four can be checked together before cutting begins. |
A CAD system arranges a style's own pattern pieces on a given fabric width, nesting odd-shaped pieces into each other's gaps to minimize unused fabric, and reports the resulting marker efficiency once the layout is complete. The software can be told to keep arranging pieces until it reaches a specified target efficiency, or simply report whatever efficiency its first layout achieves. Either way, a person still has to compare that reported efficiency, and the fabric consumption it implies, against what the order can actually afford before approving the marker for cutting.
| What can differ | The shapes you will meet | Why it matters |
|---|---|---|
| A marker built for Order A's own full 15,000-piece Make to Order run | Delta Garments builds a multi-size marker for Order A's own S M L XL ratio, reaching the fixed 93% efficiency already established for this style. | A marker efficiency confirmed once on a style's own full run becomes the reference every future marker for that style is checked against. |
| A marker built for a smaller hybrid top-up run on the same style | A 2,000-piece top-up run, ordered against forecast on top of Order A's own base quantity, uses the same pattern pieces but a smaller marker, potentially at a different size ratio. | A smaller marker can reach a different efficiency than the full-run marker, since fewer repeated pieces sometimes nest less tightly; the target still needs its own separate check, not an assumption that efficiency carries over unchanged. |
| A marker for a style with more irregularly-shaped pattern pieces | A style with a curved yoke or an asymmetric panel nests less efficiently than Order A's own simple T-shirt pieces, even with the same CAD software and settings. | A lower achievable efficiency on an irregular style is not itself a fault in the CAD system; the target consumption for that style needs its own realistic figure, not Order A's own 93% used blindly. |
| An agent verifying a factory's own reported marker efficiency before confirming a shipment's fabric cost | Meridian Sourcing asks Delta Garments to show the actual marker file and its calculated efficiency for the hybrid top-up run, not just a verbal claim that "efficiency is fine," before confirming the fabric cost in the buyer's own shipment budget. | A reported efficiency that is not backed by the marker file itself, and its own calculated fabric consumption, cannot be verified independently by an agent acting for a buyer. |
Delta Garments builds a nested, multi-size marker for the 2,000-piece hybrid top-up run, using Order A's own already-graded pattern pieces at the same S M L XL ratio. The CAD system reports the marker's own achieved efficiency at 91%, two percentage points below Order A's own fixed 93% target. Meridian Sourcing, checking this on behalf of the buyer, asks Delta Garments to rebuild the marker layout before approving cutting, since the lower efficiency means more fabric consumed per piece than the order's own fabric budget assumed.
A 2-percentage-point efficiency gap looks small on its own, but across the 2,000-piece top-up run it costs roughly USD 50.40 in fabric that a corrected marker would not consume, money the order's own fabric budget did not plan to spend.
The methodA common mistake is assuming that because a CAD system generated a marker layout, the result must already be efficient, without checking the specific percentage the software actually reports. A CAD system optimizes within whatever settings and time a person allows it; a rushed or under-configured marker run can produce a layout well below what the same pattern pieces are capable of reaching. What this costs Delta Garments is real: approving the 2,000-piece top-up run's marker at 91% instead of rebuilding it to 93% consumes roughly USD 50.40 in fabric that a five-minute rebuild would have saved.
A CAD system arranges a style's own pattern pieces on fabric to use as little fabric as possible, and tells you the percentage of fabric that layout actually uses. It does not know by itself whether that percentage is good enough for a specific order; a person still has to compare the reported number against a target already agreed for that style. If the marker falls short of the target, more fabric is consumed per piece than the order's own budget planned for, and that extra fabric has a real cost across the whole quantity being cut. Building a marker in CAD is fast; checking whether the result actually meets its own target is a separate step nobody should skip.
Delta Garments finishes building the marker for the 2,000-piece hybrid top-up run and reports it to Meridian Sourcing as ready. Karim, the production manager, sends a short update confirming the marker is complete, without stating what efficiency percentage the CAD system actually achieved.
Here is the message Karim sends to Meridian Sourcing:
Does "ready to cut" confirm the marker meets Order A's own fixed 93% target efficiency? Decide before opening the answer.
No, "ready to cut" does not confirm the marker meets the 93% target, since no efficiency figure is stated at all. Two facts missing from Karim's message decide this.
First, a marker can be technically complete, meaning every pattern piece is placed and the layout is ready to send to a cutting machine, while still falling short of the order's own target efficiency, as the 91% first attempt in this lesson's own worked example shows. "Complete" and "meets target" are two different claims.
Second, without the marker's own reported efficiency percentage stated in the message, Meridian Sourcing has no way to independently verify the fabric cost implied by this marker before approving it, and cannot compare it against Order A's own fixed 93% reference figure.
The corrected report should state the marker's own achieved efficiency percentage explicitly, alongside the target it is being checked against, before the word "ready" is used at all.
Using the figures already established in this lesson:
A single unreported efficiency shortfall costs the hybrid top-up run roughly 2.2% more in fabric than budgeted, a gap a five-minute marker rebuild would have closed entirely, at no fabric cost at all.
Open the course workbook's "Marker efficiency check" sheet. It lists a marker's own target efficiency, its actual reported efficiency, the fabric consumption each implies, and the cost difference between them, so an agent or buyer can confirm a marker before approving cutting. Enter a different order's own target and actual efficiency to see how the same check applies.

1. Delta Garments reports a marker as "ready to cut" without stating its own achieved efficiency percentage. What should happen before this marker is approved?
2. A different order's own marker is built to a target efficiency of 90%, but the CAD system reports the actual result at 88%. Using the same fabric price of USD 5.60 per kg and a fabric consumption of 0.18 kg per piece at the target efficiency, is there an extra fabric cost, and does it matter?
