Structure, grading and tension — how fabric becomes form.

3D Textile Architecture

Three-dimensional fabrics add a through-thickness yarn system to the familiar warp and weft, trading drape for delamination resistance and near-net-shape preforms.

REF-02

Pattern Grading Rules

A grade rule moves each cardinal point of a base-size pattern by a set x/y increment per size. Increments usually widen at a break point where the size range shifts.

Illustrative only. Every brand sets its own grade table from its fit model and target customer.

CAD Spec Utilities

A complete tech pack lets a factory sample without a phone call. The core sheets, in the order a factory reads them:

1. 01Flats — front, back and detail views, to scale.
2. 02BOM — shell, lining, trims, labels, with supplier codes.
3. 03POM sheet — points of measure with how-to-measure notes.
4. 04Grade table — every POM across the size run.
5. 05Construction — seam types, stitch per inch, allowances (⅜″, ½″, ⅝″).
6. 06Tolerances — commonly ±¼″ to ±½″ on major body POMs.

Tensioned Fabric Matrices

Membrane structures carry load through pre-stress and double curvature. Anticlastic (saddle) surfaces resist both uplift and downward load; panels are cut slightly undersize — compensated — so they tension into shape.
