A23 · Reference edition 2026.11
Probe access — Comparison and alternatives
A nominally clear measured feature may be inaccessible along the probe approach or withdrawal path. Include the whole inspection movement.
Scope and purpose
Compare alternatives using the same question and context. A difference in wording, layout or scale is not automatically a difference in performance. Keep the original observations available and explain which differences are meaningful for this comparison.
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
State the comparison question; align context and labels; list common features separately from differences; leave unsupported conclusions open.
