The east-facing westwork towers retain their mapped53m tops, the mapped flèche75m, and the main body28m wall datum. The official cathedral architecture page gives towers174ft/53m and cross247ft/75m above street, and the flèche117ft/35m above the ridge: the roof ridge is therefore about39.6m, not the28m OSM wall mass height. No original source height tag is changed.","https://gracecathedral.org/architecture/ supplies the street datum, concrete-and-steel structure, lead-coated copper roof and seven-bay nave. The saved Commons current east-front and western-chevet photographs were individually inspected; two pre1906 Grace Church stereographs explicitly rejected as another building. The mapped small octagonal part registers the flèche and the two real mapped front-tower polygons determine the east front.","Twin pointed belfry openings on every tower face are real air passages in both LODs. The broad pointed central entrance is recessed behind a thick portal arch; the stairs and door support stay within the saved footprint. Rose tracery, concrete piers, choir/apse, transepts, aisle roofs, clerestory and paired lancets follow the photographs. Dimensions of windows, portal, parapets, buttress caps, spire ribs and steps are proportional photo inferences, not survey measurements.","The street-relative base includes the raised front entry: published tower measurements differ by20ft between street and entry floor. The entry level is approximated at6.1m. The model does not include the surrounding hill, pavement, labyrinth, attached campus buildings or interior furnishings.","Roof panels are closed solids with visible eaves and source-faithful grey metal finish. Four opaque texture-free shared materials are used. Window panels attach to the supporting wall faces; no dark panels substitute for open tower arches. The independently authored low LOD keeps the mapped ground silhouette, both open towers, rose, roof hierarchy and flèche while reducing traceries and omitting fine roof seams/coursing."],"source":{"url":"/objects/fce235e7fef5535fbcd0cb9cf06cd43bdd3198bbfcef4dccbb3a77820ced8f32/source.blend.gz","bytes":564889,"sha256":"fce235e7fef5535fbcd0cb9cf06cd43bdd3198bbfcef4dccbb3a77820ced8f32"},"spatialSource":{"url":"/objects/7b790cf00f91f919683a6b23715095d747bb5b126d650e0ddad3e5ec3ad307bb/spatial-source.json","bytes":5980,"sha256":"7b790cf00f91f919683a6b23715095d747bb5b126d650e0ddad3e5ec3ad307bb"},"preview":{"url":"/objects/22d1a899a6c5011170d9ebe12d3e98aa6a6845aa927f6c19dff5e4aed120171b/preview.webp","bytes":9814,"sha256":"22d1a899a6c5011170d9ebe12d3e98aa6a6845aa927f6c19dff5e4aed120171b"},"previewDirection":[1.8,0.75,0.4],"revision":"33a97e04b1ffed661e0da272b63e05d6393a3cc5f4504fa0986118d886a1236e","publicationRevision":"472992fb90f97a168011e44c233ada39c123e803b00597d7039b6ab3be4bcffc","bounds":[-122.4140388,37.7916305,-122.4129547,37.7920359],"approved":false,"materialLibrary":{"schemaVersion":1,"sha256":"7afc40cf0b82b7c3c054f287817be2a37e52192aa734f187f8b20ee3277187dd","url":"/materials/7afc40cf0b82b7c3c054f287817be2a37e52192aa734f187f8b20ee3277187dd.json"},"metadata":"/assets/grace-cathedral/472992fb90f97a168011e44c233ada39c123e803b00597d7039b6ab3be4bcffc/asset.json","validation":"/assets/grace-cathedral/472992fb90f97a168011e44c233ada39c123e803b00597d7039b6ab3be4bcffc/validation.json"}
