Metal tank data for AI connection and orientation records
Heavy-gauge metal tanks form a defined Census category.
NAICS 332420 · Metal Tank (Heavy Gauge) Manufacturing
Heavy-gauge metal tanks form a defined Census category. An original drawing task can connect a connection identifier with the reference side and unit record actually supplied. Census metal-tank scope
Draw a fictional cylindrical paper vessel with three labeled external features and a reference marker. Supply a view map and component register. Ask which feature corresponds to a selected drawing callout. Include a rotated view and a later drawing revision that changes the callout numbering. The key should use the reference marker before associating a feature.
Annotate unit, feature, callout, reference direction, drawing revision and view. Hold out a new feature arrangement for evaluation. Score a callout transferred across revisions, rotational ambiguity ignored and unit identity inferred from silhouette independently. A complete case should contain the marker and effective drawing needed for a supported match.
Use original geometry and harmless props. Customer facility information, licensed designs, proprietary fabrication records and inspection material require appropriate authority and specialist review. A licensing proposal should identify the view-mapping task and checked examples. Confirm buyer requirements before preparing commercial files or commissioning further capture.

Original Fiund exercise
Translate clock positions using the fixed reference
An inert paper cylinder has three drawn locators. Its toy map contains no real vessel details or operating attributes.
| Record | Source | What it records |
|---|---|---|
| 1 | Map | Reference square at 12; feature A at 3; feature B at 9. |
| 2 | Photo | Reference square at image-clock 3; A at 6; B at 12. |
| 3 | Capture log | Prop rotated clockwise one quarter turn. |
Question for the model
Does the photo indicate a changed layout?
Show the reference answer and checks
No. With the 90° clockwise rotation in record 3, reference 12 maps to image 3, A maps 3 to 6, and B maps 9 to 12. Record 2 agrees with the transformed layout in record 1. The object's relative placement did not change.
- Comparing uncorrected clock readings
- Rotating the reference but not the attached features
Fields to preserve
- reference_clock
- Anchors object orientation
- frame_rotation
- Maps object coordinates to the image
- feature_position
- Compares corresponding locators
Test another case
Add a feature at the wrong relative position after rotation and identify only the true layout discrepancy.
Paper geometry only; exclude tank fabrication, connections, contents, ratings and service recommendations.
