Compare recorded PMI attributes
Read two STEP files locally, or open two saved PMI inventories. Compare transferred label counts and recorded raw attribute groups.
From STEP files
Up to 32 MiB per file. Both inventories are retained in the saved review. No labels observed does not prove the source has no PMI.

Recorded attribute groups
Equal groups are not matched PMI objects. Labels belong only to their own import. Count differences do not prove additions or removals.
| Kind | Raw attributes | A count | B count | B − A | A local labels | B local labels |

Unresolved attributes — excluded from grouping
Source identities
Scope and interpretation
Only recorded raw fields are compared. Units, source presence, tolerance magnitudes, standard edition, datum precedence and semantic equivalence remain unresolved. Geometry references are not compared across imports. Equal counts or attributes do not establish unchanged PMI or geometry. Unreadable values never count as unchanged. Modifier and value array order is preserved. Save the review JSON to retain both complete inventories; hashes are not authenticity certificates.
