| Know before using | 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. | The record does not create product specifications, prove fit or manufacturability, select materials or construction settings, establish legal compliance, reproduce licensed standards, or replace qualified technical, production, quality, testing, sourcing, logistics, safety, compliance, and legal review. | A company result is not a blanket approval; confirm the certificate scope, validity, facility, process, product, and transaction documentation for the exact purchase. | Community 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. |

| What the source establishes | 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. | The guide cites published ISO documented-information, garment-measurement, stitch, and seam sources plus current U.S. FTC textile and care-labeling guidance; it discloses ISO 10013:2021's current review stage, and its working record makes organization-specific requirements, suppliers, evidence, issues, and approvals explicit. | The official GOTS search exposes certified entities by country, field of operation, product category, and certification detail, including processing and trading scopes. | Threadloop'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. Current terms state that the free plan requires no card, paid upgrades start billing immediately, cancellation retains paid features through the current cycle, and the account then returns to free features. |
