| Best for | Integrated pattern, marker, and 3D production workflows | Auditing inherited grade rules or controlling a new multi-size pattern release from approved targets through sample evidence | Checking which U.S. alias the current Craft Yarn Council table gives a known metric package size before confirming project gauge | Checking GOTS certification records |
| Know before using | 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. | 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. | The 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. | A company result is not a blanket approval; confirm the certificate scope, validity, facility, process, product, and transaction documentation for the exact purchase. |

| What the source establishes | 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. | 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. | The 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 official GOTS search exposes certified entities by country, field of operation, product category, and certification detail, including processing and trading scopes. |
