Rolled steel shape data for AI section and source review
Material identification can become difficult when similar steel sections share a grade but have different dimensions or processing histories.
NAICS 331221 · Rolled Steel Shape Manufacturing
Material identification can become difficult when similar steel sections share a grade but have different dimensions or processing histories. AISC discusses identification and traceability levels. A producer can define an original task around the exact evidence its records preserve. AISC fabrication FAQ
Create fictional purchased-stock tickets, a rolling-run sheet and section drawings. Change one section dimension between order revisions while retaining the product-family name. Ask the assistant which drawing applies to the executed run and which source ticket is linked. Include a finished bundle with a readable grade but an unreadable run identifier. The key should distinguish the declared grade from the unresolved run association.
Annotate stock source, rolling event, section geometry, drawing revision and visible identifier. Hold out an unfamiliar section outline for evaluation. Score wrong-revision selection, unsupported source matching and dimensional transcription separately. A complete case should have sufficient evidence for a supported association without requiring the model to guess from shape.
Use self-authored drawings and invented reports. Customer designs, supplier documents and production-system exports need permission for the intended AI use. A licensing proposal should explain the revision-and-lineage task and independently checked examples. Confirm the buyer's accepted scope before preparing an operating archive or commissioning more capture.

Original Fiund exercise
The drawing changes mid-run, but one shape predates it
Original paper profiles show two fictional section variants without structural values.
| Record | Source | What it records |
|---|---|---|
| 1 | Section register | S2 rev A before run marker 80, rev B from 80. |
| 2 | Run sheet | Part X marker 76; part Y marker 82. |
| 3 | Photo overlay | X matches A geometry; Y also matches A. |
Question for the model
Which part is inconsistent with its effective drawing?
Show the reference answer and checks
Y is inconsistent because records 1 and 2 assign rev B at marker 82, but record 3 shows A geometry. X matches its own earlier A reference at 76. Preserve each part's run marker when labeling the comparison.
- Applying the latest revision to the entire run
- Treating identical shapes as equally correct regardless of effectivity
Fields to preserve
- run_marker
- Locates each item relative to the change
- section_revision
- Selects its drawing
- profile_observation
- Preserves actual geometry class
Test another case
Use two lines with distinct effectivity markers and require line-specific revision lookup.
No actual steel design sections, load ratings, processing controls or engineering decisions.
