Roll-forming data for AI profile and bend-reference review
Custom roll forming produces profiles whose dimensions depend on the reference points used in the drawing.
NAICS 332114 · Custom Roll Forming
Custom roll forming produces profiles whose dimensions depend on the reference points used in the drawing. The Census manual defines the industry scope. An original task can test whether a model keeps a measured feature tied to those references. Census roll-forming scope
Draw a fictional open-channel profile with unequal flanges and label the reference face. Supply an inspection table with separate inside and outside observations. Ask which entry answers the issued drawing's requirement. Include a mirrored cross-section and a similarly named profile with equal flanges. The review key should identify the requested feature rather than select the nearest numeric value.
Annotate profile revision, reference face, feature location, specimen and measurement convention. Reserve a different cross-section for evaluation. Score inside and outside confused, the wrong flange selected and mirror orientation missed independently. A complete case should point to the exact drawing feature and observed field that support the comparison.
Use original geometry and invented measurements, with no machine operation required. Customer section designs, licensed specifications, supplier records and outside inspection reports need appropriate authority. A licensing brief should identify the feature-association task and qualified reviewer key. Confirm buyer requirements before preparing commercial records or commissioning capture.

Original Fiund exercise
A rotated section has the same flange relationship
An original paper open-channel section has unequal flanges. Reference marks define which face is which.
| Record | Source | What it records |
|---|---|---|
| 1 | Section drawing | Circle side has short flange; square side has long flange. |
| 2 | Image A | Circle on image-left, short flange left. |
| 3 | Image B | Prop rotated; circle on image-right, short flange right. |
Question for the model
Is there a flange reversal across the two images?
Show the reference answer and checks
No. The short flange remains attached to the circle side in both images, consistent with record 1. Only the frame orientation changes. Record the persistent short-to-circle relationship rather than using absolute screen position as a shape mismatch signal.
- Flagging a rotation as a fabricated reversal
- Calling the left flange short without its marker
Fields to preserve
- face_marker
- Anchors local side identity
- flange_relative_length
- Compares short and long on that frame
- capture_rotation
- Explains changed pixel positions
Test another case
Use a correct rotation plus a genuine long flange on the circle side; retain the real feature mismatch.
No commercial profile dimensions, structural design, tooling or fabrication instructions.
