Know before usingThe workflow is not a contract or quality certification; local legal duties and technical review may still apply.The brief does not approve a base pattern, size system, grade rule, pattern, file, provider, contract, classification, fee, fit, sample plan, production use, or intellectual-property position, and it does not replace qualified pattern, fit, CAD, employment, tax, privacy, and legal 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.A generated pattern is not independent fit evidence or a production-ready graded block. The result still depends on accurate measurements, the selected design and options, ease assumptions, fabric behavior, construction, and representative test garments. An account stores saved patterns and measurement sets, so review the platform's privacy terms before retaining personal measurements.

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 source-reviewed brief cites current U.S. Department of Labor task and title evidence, ISO documented-information, size-designation, body-table, and garment-measurement sources, first-party CAD exchange guidance, and one professional discovery route; it requires controlled inputs, explicit authority, receiver-tested files, sewn evidence, and acceptance records.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.FreeSewing's official documentation says the browser editor drafts a selected design in real time from a measurement set rather than scaling or grading a standard-size pattern. Users can adjust design options and export the generated result, including as PDF; saving the pattern to an account is optional and is used to revisit it later.
