Dimensions 0.44 by 1.18 by 18.16 m (X by Y by Z). Metre units, +Y up, +Z front, origin on the footprint at ground level. Connectors: seat-a (hall-eaves) at (0.00, 0.00, -9.00) facing (0, -1, 0); seat-b (hall-eaves) at (0.00, 0.00, 9.00) facing (0, -1, 0). An 18.00 m lattice girder 1.10 m deep spanning the hall between the eaves columns, with thirteen verticals and twelve diagonals and a blue seating cleat at each end. Modelled with its own base at y = 0, so place it at eaves height: the seat ports then land on the column cap ports. Static geometry. Car plant palette: light grey epoxy floor, safety yellow, white plant steel, charcoal, safety orange, equipment blue, two gloss body colours, matt primer, skin, glass and emissive amber. Standard PBR materials with embedded procedural maps. Static geometry; no rig, animation, collision or navigation data.","status":"published","url":"https://3dassets.dev/assets/car-factory-production-line-hall-roof-truss-bay-c40ba8db","cdnUrl":"https://cdn.3dassets.dev/assets/27849/v1/model.glb","downloadUrl":"https://3dassets.dev/download/car-factory-production-line-hall-roof-truss-bay-c40ba8db","thumbnailUrl":"https://cdn.3dassets.dev/assets/27849/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/27849/v1/poster.webp","blurhash":"UC9%;mt8IokCt7DiWAt600M{-;ofRj_NxuIV","category":{"slug":"buildings","title":"Buildings & Architecture"},"tags":[{"slug":"modern","title":"Modern"},{"slug":"stylized","title":"Stylized"},{"slug":"interior","title":"Interior"},{"slug":"modular","title":"Modular"}],"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":19520,"triangles":408,"vertices":940,"meshes":2,"materials":2,"textures":0,"animations":[],"boundingBox":{"min":[-0.2197625592160415,0.0002294025450483711,-9.079999923706055],"max":[0.2197625592160415,1.1802522042254835,9.079999923706055]},"sizeMeters":[0.44,1.18,18.16],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Fable 5.1","downloads":4,"publishedAt":"2026-09-08T00:58:02.486Z","updatedAt":"2026-09-08T07:28:55.751Z","usage":{"threejs":"import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'\n\nconst loader = new GLTFLoader()\nloader.load('https://cdn.3dassets.dev/assets/27849/v1/model.glb', (gltf) => {\n  scene.add(gltf.scene)\n})","r3f":"import { useGLTF } from '@react-three/drei'\n\nexport function HallRoofTrussBayCarFactoryProductionLine(props) {\n  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/27849/v1/model.glb')\n  return <primitive object={scene} {...props} />\n}\nuseGLTF.preload('https://cdn.3dassets.dev/assets/27849/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/27849/v1/model.glb\" alt=\"Hall Roof Truss Bay (Car Factory Production Line)\" 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/27849/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/27849/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);"}}}
