Know before usingA unit reference; the correct allowance depends on material, seam type, and production method.The record does not reproduce licensed ISO measurement drawings, supply universal POM codes or targets, approve an internal method, prove measurement capability or product fit, or replace qualified technical-design, pattern, fit, quality, metrology, safety, and regulatory review.Patternmaking knowledge, controlled measurement files, production conventions, and sewn fit testing are still required. The software does not validate body measurements, ease, balance, grading rules, fabric behavior, construction, or product fit. The project currently labels its user wiki manual as needing updates, so confirm current commands and file behavior against the installed release and active support channels.

Source and review
What the source establishesThe linked tool or guide is maintained inside Stitch Authority and was checked against its current public interface.The guide cites current ISO garment-measurement, body-measurement, and textile-conditioning standards plus NIST measurement-process guidance for repeatability and reproducibility; it requires organization-specific codes, added points, targets, and tolerances to remain explicitly controlled.The maintained Seamly2D repository identifies the application as GPLv3+ open-source patternmaking software for Windows, macOS, and Linux. It reads multi-size measurement files for standardized sizes and individual measurement files for custom-fit work, publishes downloadable builds and releases, and links an active website and user forum.
