| Best for | Understanding what a tech pack must control before using a template or releasing work | Finding the current CYC hook and needle aliases that share one known nominal metric diameter before confirming project gauge | Integrated pattern, marker, and 3D production workflows |
| Know before using | An orientation rather than a completed product record; it does not supply a universal format, licensed standard content, measurements, tolerances, construction settings, labels, approvals, compliance conclusion, or product-release authority. | A shared nominal diameter does not make a knitting needle and crochet hook interchangeable or predict equal gauge or fabric. The reference is not a physical measurement, manufacturer inspection, UK or Canadian conversion, steel-hook chart, tool recommendation, yarn assignment, or project approval. | Pricing is not public, modules and system requirements must be confirmed, and macOS is not supported. Vendor accuracy and fit language does not prove results for an actual product. Pilot native and exchanged files with the receiving supplier, calibrated materials, approved blocks and grade rules, marker and output devices, tech-pack fields, training, version control, and risk-appropriate physical fit and production checks. |

| What the source establishes | The guide cites published ISO sources for documented-information, garment-measurement, stitch, and seam boundaries plus current U.S. FTC textile and care-labeling guidance; it discloses that ISO 10013:2021's 2026 systematic review is at close-of-review stage and separates every cited authority from product-specific technical and market decisions. | Rechecked July 28, 2026. The lookup reproduces the current public Craft Yarn Council metric and U.S. alias rows, aligns hooks and needles only when their nominal millimetre value matches, and leaves missing rows or aliases unfilled. | Optitex'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. |
