Measurements and presets
The generator starts from body or finished-detail measurements plus preset choices such as fit, silhouette, neckline, sleeve style, or dart mode.
Sewing pattern guide
How generated sewing patterns work
Nastix Patterns creates calculated drafting guides from measurements and settings. The output is useful for drafting and printing, but it still needs technical review and fitting.
Drafting calculations
Each block uses drafting rules to place construction points, curves, darts, grainlines, fold lines, and seam references.
Sewing and cutting lines
The solid line is the sewing or finished line. The dashed line adds seam or hem allowance and becomes the cutting reference.
Matching sewn edges
Edges that sew together should be checked for compatible length and shape: sleeve to armhole, waistband to waistline, inseam to inseam, and similar pairs.
Visual review
Preview helps catch obvious mistakes before export, including wrong measurements, unexpected proportions, missing allowance, or an unusual curve transition.
Printing and editing
SVG is useful for vector review and editing. PDF and tiled PDF are intended for printing, but must be checked at 100% scale.
Before cutting fabric
A generated draft is only as reliable as the measurements, settings, fabric assumptions, print scale, and final fitting checks. Treat every export as a calculated starting point.
