Know before usingThe record does not supply universal POM values, validate fit across a population, prove process capability, choose a statistical study or sampling plan, reproduce licensed standards, or replace qualified technical, fit, quality, statistical, safety, compliance, and legal review.A measurement-generated draft is a starting block, not independent evidence of body capture, comfort, mobility, balance, garment ease, or production fit. The result depends on measurement accuracy, supported ranges, formula assumptions, selected options, and output handling. Review the service's privacy terms before storing body data and sew a representative toile before design, grading, or production use.A unit reference; the correct allowance depends on material, seam type, and production method.

Source and review
What the source establishesThe guide cites current ISO, AATCC, and NIST sources for body and garment measurement boundaries, textile conditioning, dimensional-change testing, repeatability and reproducibility, and AQL-indexed sampling, while requiring the live product owner to set rather than inherit numerical tolerances.PatternLab London's current drafting page says a user creates a measurement profile, selects a basic block or sloper, adjusts fit, dart placement, length, seam allowance, and sleeve options, then downloads the generated result as tiled PDF, AI, or SVG. The live catalogue names bodice, dress, trouser, and stretch blocks and displays a price before purchase.The linked tool or guide is maintained inside Stitch Authority and was checked against its current public interface.
