ROOF TRUSS BRACINGSelected visible source evidence only; partial review, applies to depicted assembly.
Drawing notation: ROOF TRUSS BRACING
Selected visible source evidence only; partial review, applies to depicted assembly.
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.

Extraction: Reviewed · extraction partial. Partial timed visual review: Partial catalogue/OCR-first then sequential <=1000px JPEG65 locator review of public/archive/drawings/complete-upright/IMG_1324.webp. IMG_1322 additionally has one 250x435 post-schedule crop. Regions normalized in unrotated access-image coordinates; rotationDegrees is clockwise correction. Selected evidence only, no full extraction/modeling. Partial timed visual review: Additive partial high-resolution access-derivative crop review following batch13-b; original printed evidence only unless explicitly marked OCR conflict. Not full image extraction. Source is 2200x1650 upright access derivative, not master; crop has no resampling or rotation. Partial timed visual review: Prior-package and OCR audit only; no new image inspection or duplicate verified readings. Partial timed visual review: Sequential access locator and two unrotated raw-master targeted crops; additive truss and girder evidence only. Tags are printed associations and do not establish accepted physical connections. Partial timed visual review: Prior evidence reused; only selected remaining source-local regions reviewed. No historical placement or accepted physical geometry. Partial timed visual review: undefined Partial timed visual review: Source-local schedule, fabrication or connection evidence only; no installed geometry or architectural acceptance. Partial timed visual review: undefined Partial timed visual review: undefined
