Start from the released baseline
Record which file and revision were previously approved. Compare that exact baseline with the proposed revision, preserving both inputs. A filename alone is not a reliable revision identifier.
Review the scope of the change
Use Compare to inspect local geometry and assembly changes. Use supported PMI observations to identify characteristics that need attention. Record ambiguous matches rather than treating them as unchanged.
Prepare the inspection handoff
Use FAI to prepare the characteristic list and associated exports. Include the comparison evidence and unresolved questions in the change review. The responsible engineer or quality team confirms the final scope.
Where the review stops
PartDatum does not approve an engineering change order. Process changes, tooling, material substitutions and customer requirements may create additional inspection work that cannot be inferred from a CAD comparison.
