A24 · Reference edition 2026.11
Probe access — Recording and revision
A nominally clear measured feature may be inaccessible along the probe approach or withdrawal path. Include the whole inspection movement.
Scope and purpose
A reference record should allow another reader to reconstruct the intended description. Keep the identifier, context and revision together. When information changes, explain the change and retain enough of the earlier description to understand what was superseded.
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
Draw the approach envelope as a separate translucent region around the target feature.

| Scope and purpose | A nominally clear measured feature may be inaccessible along the probe approach or withdrawal path. Include the whole inspection movement. |
| Limits and interpretation | A static sketch does not prove collision-free operation on a particular machine. |
Review checklist
Check the identifier; describe the observation and its source; date the revision; link affected figures; distinguish confirmed facts from open questions.
