Get a Pattern in · 04 · grade_sizes

Grade a Pattern from a size chart

You have one size and a chart. Infer the rest of the cut.

You have a Pattern at one size (here: M) and a size chart on the Product. You want the rest of the range (XS–2XL).

This is 2D. Construction does not grade. Body is selected per size. Drape uses the Pattern of that size — you do not scale a draped M in 3D.

Steps

1. product.get → product
2. pattern.get → reference
3. pattern.grade → graded
4. pattern.preflight
5. body.select → body
6. material.get → material
7. garment.drape → run
8. garment.measure → measure
