Know before usingCommunity members add and quality-control the records, so confirm sizing, measurements, fabric suggestions, format, availability, errata, license, and purchase terms with the designer or publisher. Adding an entry to a stash does not provide the pattern files. Saved searches and private PDF storage are paid Plus features, and a listing or review does not establish pattern accuracy or fit.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 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.TUKAcad is Windows software; the official Mac route requires a separate virtual Windows environment. Pattern-piece, graded-size, marker, import and export, digitizing, and production-output capabilities vary materially by paid tier. A CAD file or marker report does not prove fit or factory readiness, so verify formats, grade rules, seam and production data, hardware, training, and downstream compatibility before subscribing.

Source and review
What the source establishesThreadloop's official guide describes an independent, fully crowdsourced database covering available and out-of-print sewing patterns. Its search supports pattern type, fabric type, age group, body type, cup size, level, format, file features, language, measurements, availability, and other filters; members can also track a stash, wishlist, projects, reviews, and discussions.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.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.Tukatech's current TUKAcad page publishes monthly Learning and Professional editions for digital patternmaking and grading, with a higher tier adding marker making, data import and export, digitizing, cut-data optimization, and yield reports. It discloses plan limits on pattern pieces, graded sizes, and marker dimensions, plus built-in help, block templates, a trial, Windows requirements, and the Windows-on-Mac route.
