Run the kit. Inspect the evidence.
Inspect recorded geometry, PMI and STEP encoding cases with the build identity and source evidence.¹
CAD REVISION COMPARE · PARTIAL FAI
Upload two STEP revisions; PartDatum finds what changed and builds the delta-FAI report for only those characteristics — in minutes, in your browser.
Review geometry and readable PMI changes, enter measurement results, and prepare AS9102, PPAP Element 9 and QIF exports with an engineer-reviewed scope.¹

PROOF
Don’t trust us. Test us.
Every claim below comes with the evidence to check it.
Overlay. Re-balloon. Re-measure everything. Or don’t.
From manual revision review to one inspection-preparation workflow.¹
| The old way | With PartDatum |
|---|---|
| Hunt for changes by eye | Find changes automatically |
| Move balloons by hand | Numbers carry over |
| Re-measure the whole part | Focus on affected characteristics |
| Miss a tightened tolerance | “Requirement changed 0.05 → 0.03” |
| Drawings + Excel + email | One package: Forms 1–3, Element 9, QIF, evidence |
THE WORKFLOW
Compare STEP files. Review the change. Prepare the handoff.
- 01
Load the revisions
Select a baseline and a candidate. Start with a public example or use your own permitted files.
- 02
Review geometry and PMI compare
Compare geometry and PMI. See placement, shape and requirement changes together.
- 03
Assess AS9102 revision change and ECN impact
Move from changed features to affected characteristics, delta FAI preparation and ECN review.
- 04
Prepare the handoff
Export inspection records and evidence for the next stage of your quality process.

PARTDATUM
Turn a revision into an inspection review.
Start with a public example. Review the scope before using your own permitted files.
Scope & limits
- Confirm the final measurement scope with your engineer. Missing PMI, unresolved associations and unsupported content remain explicit; preparation records are not approved inspection results.
- Current-build kit results will be shown when the application publishes a public results file.
- Results belong to the recorded build and platform. NIST test data does not imply NIST endorsement.
- Validation covers defined geometry, PMI and STEP-encoding cases; a pass is not proof that every possible change will be detected. Numeric ISO 286 limits-and-fits lookup is not bundled.
- Balloon continuity applies to supported revision tracking and resolved associations. New-feature numbers are proposals and require engineer approval. Explicit numbering choices and unresolved matches remain part of the record. A proposed number is not an assigned inspection requirement.
- STEP AP203, AP214 and AP242 are supported. For multi-file STEP assemblies, include all referenced files together or in a ZIP archive. STL/OBJ are mesh inputs only. Native CATIA, NX, Creo and SolidWorks files and IGES are not currently supported; export STEP AP242 from your CAD system.
- Without readable semantic PMI, geometric changes can produce candidate re-measurements, not approved nominal requirements or tolerances. Missing values, unreadable requirements and ambiguous geometry-to-characteristic links require an engineer decision.
- Geometry observations describe the recorded surface samples. A below-threshold result is not exact shape equality. Final measurement scope may also depend on tooling, process, material and customer requirements that a CAD revision cannot establish.
- AS9102 Forms 1–3 are preparation data sheets; not all Rev C form fields are included yet. Form 2 is a preparation template. Users enter measurements and approve requirements before submission. PPAP Element 9 and ECN outputs support preparation and review; they do not decide resubmission or approve PPAP. Typed QIF output depends on available source semantics; missing semantics are not invented.
- The tightened-tolerance example “Requirement changed 0.05 → 0.03” illustrates a readable requirement change. It is not a customer result, a guaranteed import outcome, or an assertion that all GD&T is readable.
- Application images come from the accepted R71.1 native browser run using public test data. Each image is bound to its source evidence in the claim ledger.
