# Nestproof

Your graded patterns, open in your LA factory's system in every size, and signed off before the cut.

Tell us what the factory asked for and what you have. We draw up the transfer scope, the checks your factory signs off, and who fixes what. Terms follow by email.

Served: brands anywhere in the United States, for transfers to factories in Los Angeles, California.

## How to start

Describe, in your own words, **what the factory asked for, and the pattern files you have**: software, sizes, pieces per style, dates, and who you want doing cleanup. your own words are fine. The page draws up a proposed transfer scope before it asks for an email. Then **Send for terms**: the request is recorded with a reference and a private link, and Nestproof emails nonbinding terms, the sign-off plan for your factory and the questions still open. Nothing is transferred, priced or signed off until you agree terms.

Example words: "Two styles (wrap dress, 9 pieces; wide-leg pant, 7 pieces), graded XS-XL, made in Gerber AccuMark by our former patternmaker. We have AAMA DXF + RUL zips. Factory in downtown LA cuts on Optitex and wants AAMA DXF in inches with grading, seam allowance included. Need files accepted by Dec 4, 2026; cutting starts Dec 8, 2026. Please handle any cleanup and get the factory to sign off."

Another: "We designed in CLO, have the .zprj and a tiled PDF, sizes S/M/L (I think graded in CLO). Factory said 'just send Gerber files'. Our patternmaker moved away. Need this in 5 business days. They might need markers too? Fabric is 58 in."

## Example scope (from the first example)

```
PROPOSED TRANSFER SCOPE: AccuMark to Optitex, 2 styles, XS to XL
From: Gerber AccuMark, AAMA DXF, RUL rule file included
To: Optitex, AAMA DXF, graded, Inches, Seam allowance included
Styles and pieces: Wrap dress 9, Wide-leg pant 7; 16 pieces
Size run: XS to XL (5 sizes: XS, S, M, L, XL)

If a check fails: If a check fails, Nestproof fixes the file problem and re-checks it before the factory sees the files again. Anything that changes fit or grading comes back to you first.
Pattern changes: not chosen; file repair only until you approve changes
Markers: not included unless you ask
Dates: files to factory open; factory sign-off December 4, 2026; cut or sample December 8, 2026
Days between sign-off and cut: 4
Sign-off means: 1 scale true on a named measurement; 2 every ordered size present in the nest; 3 notches and grainlines arrive as notches and grainlines; 4 contours closed, no duplicate lines; 5 piece names and cut quantities readable, count matches; 6 the named person at the factory confirms by the sign-off date.
Confirms at the factory: to name
Separate deliverables: markers (only if requested); pattern work such as grading a new size or fit changes (only with approval).
```

Open before we start:

1. Who at the factory signs off the files? Usually the sample and development manager or the pattern room. [You: You name them, or we ask the factory with your go-ahead.]
2. The patterns are yours to share with Nestproof and the factory. [You: You confirm when you reply.]

## What "signed off" will mean

1. Scale true on a named measurement (Nestproof checks; the factory confirms on import).
2. Every ordered size present in the nest (Nestproof; factory).
3. Notches and grainlines arrive as notches and grainlines (Nestproof).
4. Contours closed, no duplicate lines (Nestproof).
5. Piece names and cut quantities readable; count matches your list (Nestproof; factory).
6. The person you name at the factory confirms by the sign-off date (you name them, or we ask with your go-ahead).

If a check fails, what happens follows the cleanup owner you choose. Nestproof: we fix the file problem and re-check it before the factory sees the files again. Your patternmaker: we report exactly what failed, they fix it, we re-check. The factory's pattern room: we report what failed and they fix it inside their system. If your choice conflicts with what you wrote (for example, you wrote that your patternmaker moved away), it stays an open item until you confirm who. Anything that changes fit or grading comes back to you first. Three dates stay separate: files to factory, sign-off target, cut or sample date.

## Three deliverables, kept apart

- **Pattern transfer**: in scope.
- **Markers**: a separate job, only if you ask. It needs the cutting-table length, fabric width and size ratio.
- **Pattern work** (grading a new size, fit changes): only with your approval.

## Who owns the factory check today

- **Your original patternmaker re-exports.** Good at: Knows the pattern, the grade rules and the seam allowances, and can fix pattern logic. Leaves open: Nobody watches the import at the factory, so you relay errors between them. Export settings can drop grading or notches.
- **The factory's pattern room re-digitizes.** Good at: One counterparty, and the output is native to the cutting system. Leaves open: The work lives in that factory. Ask whether you get the converted files back, and see what changed against your approved pattern.
- **A pattern room converts per style.** Good at: Local trade skill, and plotting if you also need markers. Leaves open: Ask whether the commitment is the factory accepting the files, or the file format alone.
- **You manage it by email and a spreadsheet.** Good at: No cost, full control. Leaves open: Without CAD you cannot check scale or the nest, so problems surface at the cutting table.

## Choices only you make

- Who fixes file problems: Nestproof, your patternmaker, or the factory's pattern room.
- Pattern changes: file repair only, or fit and grade changes with your approval.
- Markers: not needed, quote them too, or not sure yet.
