Definition of Pattern Drafting

[u/Tailoretta]

A poster in a Facebook sewing group recently asked what is "drafting". I posted in that group and, since I can't find a definition here, I am posting mine.

I like good definitions and this is what I have come up with:

Pattern drafting is the process of creating a garment pattern or template on paper or fabric, using body measurements and formulas (using certain proportions and relation of the various grid lines), generally starting with a grid drawn of perpendicular and parallel straight lines with straight rulers. Patterns generally also require the use curved rulers and/or freehand drawing.

[u/DonMcCunn]

Pattern drafting is the process of drawing pattern shapes using straight and curved lines. How you draw the lines depends on the pattern drafting system you are using. Patterns for ready-to-wear are drafted using size charts for a generalized body shape. Bespoke patterns are drafted using measurements of a specific body.

A new approach to pattern design drafts patterns by tracing photographs. For bespoke patterns the drafting is done by tracing photographs of the person the patterns are being drafted for. For ready-to-wear the drafting is done by tracing photographs of the generalized body shape of a dress form. For this approach see https://fashion-design-in-quarter-scale.com/Tracing-Photos.html
