Apparel CAD Pilot Checklist

A product-neutral, fillable checklist for testing pattern CAD, grading, 3D, markers, and supplier file exchange on one representative style.

Current first-party apparel CAD documentation reviewed for DXF and grading exchange, units, print output, import and export behavior, and representative round-trip testing; no universal interoperability claim is made.

How guide evidence works

The pilot is a file handoff, not a software demo

“Supports DXF” does not mean two systems will interpret every pattern element the same way. Units, size names, grade rules, seam allowances, notches, internal lines, piece quantities, curves, annotations, and companion files can change or disappear if import settings or versions differ.

Official product documentation makes the risk visible. Browzwear's DXF import tutorial tells users to verify units, size multiplier, piece display, and measurements in preview. CLO's support materials explain that grading can depend on a companion RUL file with the same name and folder location as the DXF. Optitex publishes support material for standard CAD exchange and separately offers converters. These are normal workflow details, but they show why a format name is only the beginning of an interoperability test.

Choose a style that can expose failure

The pilot style should be small enough to finish but complex enough to represent the real work. Include multiple pattern pieces, at least one curved seam, a notch or drill point, internal construction lines, seam allowance, annotations, more than one size, a grade rule, and any element the business cannot afford to lose. If markers, artwork, pleats, darts, stripe matching, or 3D material behavior matter in production, the pilot needs them too.

Decision rule

Write the pass criteria and expected measurements before anyone opens the new software. A pilot that changes its definition of success after seeing the output is a demonstration, not a test.

Decision and owners

Name the business decision, participants, and non-negotiable downstream use.

Software, edition, and exact versionPilot decisionPilot owner and operatorsRequired downstream recipientsPass threshold and decision date

Representative style

Use a production-like style, not the vendor's clean sample file.

Style name, number, category, and base sizeWhy this style is representativeExpected piece list and piece quantitiesCritical geometry and metadataExpected sizes and grade-rule source

Source package

Freeze the input so every result can be reproduced.

Native source files and versionsExchange filesUnits, scale, coordinate/origin, and naming conventionExpected control measurementsUntouched archive createdNever troubleshoot against the only source copy

Import fidelity

Preview, count, and measure before editing anything.

Piece count, names, quantities, and categories matchNo duplicate, missing, flattened, or silently renamed pieceUnits, scale, orientation, and origin matchControl measurements fall within the stated toleranceCurves, corners, darts, pleats, and cutouts matchInspect both visually and numericallyNotches, drill points, internal lines, grainlines, and labels matchRecord any conversion or remappingSeam allowance is preserved or intentionally rebuiltCheck corners, variable widths, and enclosed shapesImport exceptions and screenshots

Editing and measurement

Test the work people actually perform after import.

Required edit sequenceMatched seam and walk tools produce expected lengthsInclude ease or gathering rules where relevantMeasurement reports match control valuesState tolerance and measurement methodUndo, version naming, and recovery testedRecover both an accidental edit and a prior approved stateObserved time and training friction

Grading

Check the rule data and the resulting geometry. A smooth nest can still miss target measurements.

Size names, order, base size, and grade-rule values matchConfirm companion rule files loaded where requiredCritical internal elements grade as intendedPockets, notches, button positions, artwork, and drill pointsNested outlines progress without unexplained jumpsInspect every piece, not only the bodiceGraded points of measure hit targetsCheck representative sizes at both ends of the rangeNon-linear rules or range breaks are preservedIf not in scope, mark not applicable and explainGrade exceptions

3D and material work

Complete only when 3D output is part of the buying decision. Simulation does not replace physical validation.

Export and receiver reopen

The receiving party performs this check in its own environment.

Plot, marker, or cut output

Use the real output device or service when this step matters to production.

Operational fit and decision

A technically capable tool can still fail the team on hardware, support, cost, or ownership.

What counts as a pass

A pass means the designated people can complete the intended work and the receiving party can use the result without an undisclosed loss. It does not require every format to be perfect. It does require every transformation to be known, repeatable, assigned to someone, and cheap enough to live with.

Reject or retest when a critical element disappears silently, a receiver cannot reproduce the expected scale or grade, a workaround depends on one person's memory, archived work becomes inaccessible without the subscription, or the team cannot state which file is authoritative after a revision.

Limit

This checklist does not rank CAD products and does not validate garment fit, grade-rule strategy, cybersecurity, or legal terms. Software output depends on source data, settings, versions, operator skill, hardware, and the receiving system. Physical samples and qualified pattern or technical review remain necessary where fit, safety, or production risk warrants them.
