Every dimension belongs to an object and a drawing. Original room numbers, object marks, printed values and source regions stay together—even when the answer is unresolved.
464 of 464 photographs have extraction records, containing 27,517 properties. Initial image review is not exhaustive extraction: 0 photographs have passed the full-region check. 66 numbered sheets are reconciled. Modeling and architectural registration are separate work; these counts do not establish a complete building.

Printed values, calculations, image traces and observed counts are different kinds of evidence. “Verified” applies to the specific reading—not to the whole room or model.
14 ft
Endpoints: structural/grid axis or centerline → next structural/grid axis or centerline. The 14-foot bay is not a room-clear width.
Drawing notation: 14′-0″ / 4′-0″ / 6′-0″ / 4′-0″
Source-space candidate only; no pixel-distance conversion or accepted world transform.
4 ft
Endpoints: structural/grid axis or centerline → facade opening jamb face. The 14-foot bay is not a room-clear width.
Drawing notation: 14′-0″ / 4′-0″ / 6′-0″ / 4′-0″
Source-space candidate only; no pixel-distance conversion or accepted world transform.
6 ft
Endpoints: facade opening jamb face → opposite facade opening jamb face. The 14-foot bay is not a room-clear width.
Drawing notation: 14′-0″ / 4′-0″ / 6′-0″ / 4′-0″
Source-space candidate only; no pixel-distance conversion or accepted world transform.
