B35 · Reference edition 2026.11
Grain and fold direction — Review and interpretation
The relationship between material direction and fold direction belongs in the construction record. Keep it visible when the outline is rotated.
Scope and purpose
Review the record before drawing a conclusion. Look for missing context, ambiguous labels and claims that exceed the evidence. The purpose is to identify what can be understood from the record and what still requires a separate assessment.
Working notes
This collection describes enclosure forms, access routes and documentation practices for paper-based material. It is intended for reading and planning, not for directing treatment of fragile objects. Fold diagrams and record examples are original illustrations with no associated collection or accession data. Material descriptions distinguish observed features from documented properties. Decisions about a real object, its condition and its environment require the relevant professional judgement.
Practical example
Place a direction arrow beside the flat pattern and repeat it on the assembly sketch.

Review checklist
Read the record without relying on memory; check every label; identify uncertainty; decide whether a specialist review is required; retain the original observation.
