| 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. | A unit reference; the correct allowance depends on material, seam type, and production method. | It is one curator's intentionally selective, off-Ravelry-oriented database, inventories change, and paid supporters can receive rotating priority placement; verify availability, fibre claims, shipping, and terms directly. |

| 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 linked tool or guide is maintained inside Stitch Authority and was checked against its current public interface. | The individually researched database offers free listings and sortable yarn, fibre, designer, editor, accessory, and location views; the EU page spans multiple countries and direct seller profiles. |
