Know before usingThe reference is not a dimensional measurement, manufacturer inspection, UK or Canadian conversion, steel-hook chart, tool recommendation, yarn assignment, gauge result, or proof that a proposed tool will produce the required fabric.The record does not create a production grade, supply universal increments or breakpoints, validate a CAD file or fit population, reproduce licensed standards, or replace qualified anthropometric, pattern, technical-design, fit, quality, accessibility, safety, statistical, and user-research review.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.The page does not publish price and its product-quality, error-prevention, data-loss, and fit statements are vendor claims. Capabilities vary across Essential, Classic, Expert, 3D, and add-ons. Confirm licenses, modules, support, system and file requirements, then pilot approved blocks, grade rules, supplier reopen, material and mannequin data, plot or cut outputs, and risk-appropriate physical fit and production checks.

Source and review
What the source establishesThe lookup reproduces the current public Craft Yarn Council metric and U.S. alias rows and follows the Council's warning that company letter and number labels vary; blank aliases remain blank instead of being inferred.The guide cites current ISO body-table, size-designation, and garment-measurement boundaries plus two peer-reviewed studies that tested the relationship between conventional grade rules, anthropometric evidence, and garment fit; it requires product-specific target deltas and validation instead of publishing universal increments.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.Lectra's current Modaris page identifies version 2025.2 as the latest listed release and describes a one- to three-year subscription with two releases per year. The modular range covers base-pattern creation and modification, grading and industrialization, native-file supplier work, pattern libraries, synchronized 2D and 3D prototypes, configurable or imported mannequins, and separate conversion and consumption-estimate add-ons.
