Overall 1.54 by 4.06 by 3.44 m (X by Y by Z). Metre units, +Y up, the working face toward +Z, resting on y=0. The flight rises toward -Z from its foot at the origin, so the top tread lands one riser under a deck set at 3 m. Static flight; the treads, stringers and rails are one rigid assembly. Static geometry; no rig, collision or navigation data. Original CC0 geometry: no maker, courier or brand marks anywhere, and every livery and sign is invented.","status":"published","url":"https://3dassets.dev/assets/parcel-depot-and-sorting-hall-parcel-depot-and-sorting-3de951d6","cdnUrl":"https://cdn.3dassets.dev/assets/34822/v1/model.glb","downloadUrl":"https://3dassets.dev/download/parcel-depot-and-sorting-hall-parcel-depot-and-sorting-3de951d6","thumbnailUrl":"https://cdn.3dassets.dev/assets/34822/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/34822/v1/poster.webp","blurhash":"U67K_3x]00IASjDiV=_48^jD?vbxM{%NtRD$","category":{"slug":"buildings","title":"Buildings & Architecture"},"tags":[{"slug":"modern","title":"Modern"},{"slug":"realistic","title":"Realistic"},{"slug":"interior","title":"Interior"},{"slug":"kit","title":"Kit / Set"}],"license":{"slug":"cc0-1.0","name":"CC0 1.0 Universal","url":"https://creativecommons.org/publicdomain/zero/1.0/","attributionRequired":false},"contributor":{"username":"3dassets","name":"3D Assets","url":"https://3dassets.dev/u/3dassets"},"stats":{"fileSize":18560,"triangles":360,"vertices":828,"meshes":3,"materials":3,"textures":0,"animations":[],"boundingBox":{"min":[-0.7700085343303769,0,-3.2375112169761264],"max":[0.7700085343303769,4.059999942779541,0.1975111657161317]},"sizeMeters":[1.54,4.06,3.435],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Opus 5","downloads":0,"publishedAt":"2026-09-11T10:16:29.836Z","updatedAt":"2026-09-11T10:16:29.949Z","usage":{"threejs":"import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'\n\nconst loader = new GLTFLoader()\nloader.load('https://cdn.3dassets.dev/assets/34822/v1/model.glb', (gltf) => {\n  scene.add(gltf.scene)\n})","r3f":"import { useGLTF } from '@react-three/drei'\n\nexport function MezzanineStairFlight3MRiseParcelDepotAndSortingHall(props) {\n  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/34822/v1/model.glb')\n  return <primitive object={scene} {...props} />\n}\nuseGLTF.preload('https://cdn.3dassets.dev/assets/34822/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/34822/v1/model.glb\" alt=\"Mezzanine stair flight, 3 m rise (Parcel Depot and Sorting Hall)\" camera-controls auto-rotate></model-viewer>","blender":"# Blender 4.x: File > Import > glTF 2.0, or from the Python console after downloading the file.\nimport bpy\nbpy.ops.import_scene.gltf(filepath='model.glb')  # from https://cdn.3dassets.dev/assets/34822/v1/model.glb\n# Metres and +Y up are converted to Blender's Z-up scene automatically.","godot":"# Godot 4: copy model.glb into res://models/ and the editor imports it as a scene.\nvar packed := load(\"res://models/model.glb\") as PackedScene\nvar model := packed.instantiate()\nadd_child(model)","unity":"// Unity: import model.glb with glTFast (Package Manager: com.unity.cloud.gltfast) and drag the prefab in,\n// or load it at runtime straight from the CDN:\nusing GLTFast;\nvar gltf = new GltfImport();\nif (await gltf.Load(\"https://cdn.3dassets.dev/assets/34822/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);"}}}
