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.
4 count
Count of W3 plan symbols only. This is not a W-218 type quantity and not an as-built count.
Drawing notation: DESK; DESK; DESK; DESK
All four DESK symbols lie within the plan field explicitly labeled PUBLIC LOBBY, not in the east vestibule, Main foyer, Broadway foyer or postal work space.
Drawing notation: PUBLIC LOBBY
0 degrees-from-positive-X-axis-undirected
All four W3 symbol rectangles have their long sides page-horizontal. This is an axis, not a directed facing. A 180-degree equivalent cannot be distinguished from W3.
Drawing notation: DESK
41.851 ft-Z
Describes plan alignment only; it does not establish a fabrication or survey centerline. Provisionality is inherited from the four source picks and f1-w3-registration-01.
Drawing notation: DESK; DESK; DESK; DESK
Merged source region for the four centers used by this derived row-alignment calculation.
Calculated from: f1-public-lobby-desk-plan-01-world-z, f1-public-lobby-desk-plan-02-world-z, f1-public-lobby-desk-plan-03-world-z, f1-public-lobby-desk-plan-04-world-z
The room/function wording and coordinated 1933 sheet set make W-218 the leading candidate type. W3 supplies no W-218 reference, detail bubble or type mark, and W-218 supplies no installation schedule or keyed plan symbol. Similarity and later photographs cannot promote the candidate to a verified type assignment.

Numeric value unresolved
Design drawings are not an as-built survey. The 1983 HABS narrative and photographs are retained only as later corroboration, not as proof of the 1933 installation act.
Drawing notation: DESK; DESK; DESK; DESK
W3 is design-plan evidence only and therefore cannot close the as-built quantity property.
Source inventory is separate from the floor filters above. Select one drawing to inspect it; no drawing set is preloaded.
