A47 · Reference edition 2026.11
Layout changeovers — Layout and sequence
A repeatable changeover record identifies which items stay, which move and which are replaced. It also records the previous valid arrangement.
Scope and purpose
Place the relevant elements in a visible order before completing the record. A diagram should distinguish position from sequence and should preserve the orientation used in the written notes. Review the example for a practical way to make the relationship explicit.
Working notes
This reference collection concerns light, offline dimensional-inspection layouts. It brings locating concepts, component descriptions and revision records together without substituting for an engineered fixture design. The drawings are original explanatory diagrams. Reference IDs identify documents, not commercially tested products. Read the scope and limitations alongside each example, and keep the actual part drawing and inspection requirements available when reviewing a proposed layout.
Practical example
Compare two layout revisions with unchanged, relocated and replaced component lists.

| A47 | Layout changeovers |
| Scope and purpose | A repeatable changeover record identifies which items stay, which move and which are replaced. It also records the previous valid arrangement. |
| Limits and interpretation | Matching part names do not prove that an old layout is still suitable. |
Review checklist
Identify the starting condition; mark the order or orientation; check that labels in the figure match the accompanying table.
