Plastic profile data for AI cross-section and reference-face checks
Extruded plastic profiles can share an overall envelope while differing in a small internal feature.
NAICS 326121 · Unlaminated Plastics Profile Shape Manufacturing
Extruded plastic profiles can share an overall envelope while differing in a small internal feature. The Census manual defines the profile-manufacturing scope. An original exercise can make the comparison depend on a specific drawing and reference face. Census plastics profile scope
Draw two fictional profile sections and create harmless paper or printed props. Give one profile an offset channel and mark the reference face in the instruction. Ask the assistant which observed section matches the issued drawing. Include a mirrored view, a superseded drawing and a finished-length ticket whose section identifier is absent. The key should separate the visible geometry finding from the unresolved ticket association.
Annotate section identifier, reference face, feature location, drawing revision and evidence view. Hold out an unfamiliar profile outline for evaluation. Score mirrored orientation, use of the old drawing and identity inferred from dimensions alone independently. A complete case should provide enough evidence for a supported section match.
Use original designs and invented records. Customer dies, licensed profiles, material declarations and production-system exports need permission for the intended AI use. Describe the geometry-and-evidence task and independent key to prospective buyers. Their accepted brief should guide further document preparation or authorized capture.

Original Fiund exercise
Two lengths taken from opposite faces
The contributor draws original stepped profiles. A mock cut record uses offsets measured from a marked face.
| Record | Source | What it records |
|---|---|---|
| 1 | Drawing | Feature F at 12 mm from marked face on a profile 30 mm wide. |
| 2 | Cut sheet | F recorded 18 mm from unmarked face, on the same axis. |
| 3 | Photo | Marked face and F visible; no independent scale in image. |
Question for the model
Do the coordinates necessarily conflict?
Show the reference answer and checks
No. With the same width and axis in records 1 and 2, 30 − 18 gives 12 mm from the marked face. Record 3 supports the identity of the reference feature but cannot independently quantify the distance. Retain the original coordinate origins.
- Comparing offsets without transforming their origins
- Using an unscaled photo as a dimensional measurement
Fields to preserve
- reference_face
- Defines coordinate origin
- measurement_axis
- Ensures the offsets share a line
- profile_width_mm
- Allows conversion between opposite origins
Test another case
Change the second record to a different width variant; require confirming the actual width before transforming its offset.
No proprietary extrusion profiles, machine setups or actual cutting tolerances.
