Confirm the inputs
Ask for a revision identifier, the source CAD version, the export protocol and the intended unit. Preserve the delivered files before conversion or repair.
Compare the delivered geometry
Review component correspondence, changed surfaces and the available PMI. Check coordinate frames before interpreting a moved component as a shape change.
Return a precise review record
Use the report to identify the affected region or characteristic. Separate an observed difference from missing export information, and request a corrected file where necessary.
Keep commercial acceptance separate
A comparison can support a supplier discussion. It does not establish that a delivery meets every drawing, purchase-order or quality-system requirement.
