| Know before using | 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. | Certification bodies maintain and verify the published scope-certificate data. A listed scope certificate does not establish that a particular shipment has a valid transaction certificate, that every product or site is in scope, or that the company has suitable capacity, availability, performance, commercial terms, or project fit. Confirm the exact standard, organization, sites, products, validity dates, scope, and applicable transaction certificate before relying on a claim. |

| What the source establishes | 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. | Textile Exchange states that this registry combines current scope-certificate data supplied by active certification bodies so users can confirm whether an organization is certified and inspect its certified materials, products, and sites. Its separate authentication guidance directs users to authenticate transaction certificates for certified shipments rather than treating a company-level scope certificate as proof of a particular transaction. |
