TRACEWORK — Split collar / TW–02
FICTIONAL ILLUSTRATIVE DOSSIER — NOT A PRODUCTION SPECIFICATION

A split ring-like concept for discussing how an assembled condition should be described. The gap, bore and fastening context matter together; an isolated product image cannot define their relationship.

The split collar is a fictional interface study. It is useful when a buyer has a physical reference but the conditions of that reference are not clear. A free-state sample, an assembled sample and a drawing can express different information; do not silently treat them as interchangeable.

OPEN QUESTIONS
State of the part: Clarify whether the discussion concerns the unassembled part, a specified assembly condition or an installed reference. Do not invent a force or torque.
Mating context: Identify which companion part or interface is relevant. If that information is not available, keep the fit question open rather than choosing a tolerance.
Reference limits: A surface appearance sample may not be a dimensional master. Write down the sample purpose and who can resolve conflicts with the drawing.

SAMPLE CONTEXT
Ask the sample owner to describe its assembly state and intended use in the review. If the sample was altered, used or obtained without a drawing history, record that limit alongside the sample reference.

INSPECTION CONTEXT
Ask what condition should apply during inspection and how the report should describe it. Any fixture, method, sampling plan or acceptance criterion needs responsible review. This dossier supplies the questions, not an inspection specification.

HANDOVER
Drawing identifier and controlling revision
Description of the relevant assembly condition
Mating-part reference or an explicit unknown
