Cut-ready fabrication

Deliver physical-part geometry that preserves design intent and is verified for its stated production stage. File validity, downstream interpretation, and physical qualification are separate claims. For audit-only work, report findings without changing or uploading artifacts.

Route by deliverable

Load only the references needed for the next decision:

• Missing controlling inputs, reconstruction, or revision scope: intake and revision.
• Parametric/scripted geometry, variants, or new export formats: CAD generation.
• Profile cutting, vinyl, stencils, or operation paths: 2D preflight.
• Printed physical artwork and contour-cut products: production graphics.
• Solid CAD, formed sheet, or CNC parts: 3D preflight.
• Print meshes, configured slicer projects, or inspected slices: additive preflight.
• Producer requirements, finishing, upload previews, or physical proofs: vendor handoff.

Required outcomes

1. Define the part and production stage. Establish process, material/stock, units, critical geometry, interfaces, tolerances, finish, and target producer as relevant. Distinguish CAD bodies from separate physical parts and intended joins. Reuse accepted inputs; ask only when an unknown controls the next geometry, fit, output, or safety decision. Continue independent work with clearly bounded assumptions.
2. Preserve design authority. Identify the accepted base and controlling specification. Derive variants and exports from them; freeze everything outside the requested revision. Declare process-specific transformations rather than silently rebuilding or changing the part. Keep measured, specified, calculated, reconstructed, and assumed inputs distinguishable.
3. Prove the final geometry. Independently import/read the actual exported bytes. Compare units, transforms, bounds, topology, expected feature inventory, critical dimensions, orientation, and operation assignments with the specification. Measure features rather than copying nominal values into a report. Diagnose missing features, unexplained healing, or changed geometry before accepting the file.
4. Inspect the actual result. Render the imported export from views or sections that expose its critical shapes, coverage, openings, and clearances. Compare reference-derived work in comparable views, including adjacency, axes, silhouette, and negative space. Separate geometry defects from tessellation, normals, or display artifacts; a convincing preview does not prove the part is correct.
5. Verify the requested downstream stage. Apply the selected process checks. Use current official requirements for the exact producer, material, and service where they affect the result. Inspect actual vendor/slicer interpretation when that stage is requested and available. Never infer printability, machining simulation, or physical fit from a successful import.
6. Release the exact checked revision. After corrections, regenerate derivatives and repeat affected checks. For substantial or consequential geometry changes, obtain an independent review of the brief, source evidence, and raw exports without seeding expected findings; report if unavailable. Deliver the requested files, editable source when needed, useful preview, and concise evidence/gaps. Verify a hosted preview or uploaded artifact identifies the same part, variant, and revision.

Boundaries

• Preserve the original and explain any manufacturing change outside scope before making it. A format conversion is not permission to redesign.
• Use source-backed process limits. Do not invent tolerances, clearances, bend rules, tooling limits, or printer settings. Do not apply kerf, shrink, bend, or finish compensation unless the workflow explicitly requires it; prevent double compensation.
• Do not laser-process ordinary PVC/vinyl. Use a suitable non-laser route unless the exact material and machine operator explicitly establish laser compatibility.
• Keep production geometry free of proof-only overlays and render-only repairs. Do not conceal missing physical features with caps, shading, or hidden bodies.
• Upload, order, proof approval, and machine execution are separate actions. Stay within the user's authorization; this skill does not authorize them.

Handoff status

Give a concise status for each materially different artifact/process, followed by passed checks and material gaps:

• Ready for the stated stage: All applicable digital and downstream checks for that named stage passed. Name the stage, such as cut-file handoff or inspected slice; do not imply physical qualification.
• Locally preflighted: Geometry/export checks passed; required vendor, slicer, or other downstream interpretation remains unverified.
• Draft / reconstruction: Intent or controlling inputs remain provisional.
• Blocked for the stated stage: A missing input or failed check can materially change the part or make that stage unsafe.

Report fit/performance proof separately as performed, unperformed, or not applicable with a reason. Where uncertainty or failure consequence warrants a physical proof, identify the relevant coupon, prototype, or first-article check. A digital pass cannot stand in for it; honest limited-stage delivery may still proceed.
