Preserve the engineering context
An archive needs more than a model file. Keep revision identity, units, source-system context, required metadata and validation evidence in the preservation package.
Review a retrieved model
Compare available baseline and retrieved geometry, then inspect the supported PMI. Retain the method and unresolved findings so a later reviewer can understand what was assessed.
Use PartDatum within a wider process
Compare can provide revision-review evidence. It is not an archival repository, retention service or implementation of the complete LOTAR process.
Avoid an unsupported compliance claim
LOTAR defines preservation and retrieval processes. A STEP export, checksum or visual comparison alone does not demonstrate conformity with every applicable archival requirement.
