Source and review
What the source establishesOptitex's current page describes 2D pattern creation, grading, verification, Tech Pack Essentials, marker creation and nesting, cut and plot output, 3D virtual samples, fabric simulation, colour and print placement, tension maps, and avatar editing. Its support page lists native and standard CAD interchange routes and states that Optitex does not support macOS.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.The guide cites current ISO sources for documented-information, garment-measurement, stitch, and seam boundaries plus current U.S. FTC textile and care-labeling guidance; it explicitly separates those authorities from product-specific technical and market decisions.
