| Best for | Digital pattern drafting | Approving a named sample without accidentally approving bulk |
| 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. | The record does not validate every size or user, prove bulk conformity, prescribe universal defect classes or AQL, replace testing or inspection, or establish compliance. |

| 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. | The record applies version and lot controls from textile testing plus current ISO and ASQ acceptance-sampling boundaries to separate sample approval from bulk release. |
