{"data":{"id":"28842","slug":"medieval-siege-and-castle-defence-machicolation-course-c6b290ca","title":"Machicolation Course (Medieval Siege and Castle Defence)","summary":"Corbelled stone course for a wall head over a gate: five brackets, four drop openings and a crenellated parapet above.","description":"A 4 m corbelled course that oversails a gate. Five stepped brackets carry four slab strips with real drop openings between them, and a crenellated parapet stands on the course, so the ground below a gate can be covered from directly overhead. Sets on the wall head of the 4 m bays. Dimensions 4.00 × 1.82 × 1.49 m (X × Y × Z). Ground-contact origin under the footprint. Metre units, +Y up, +Z forward. Kingdom limestone, ashlar, timber, oak, iron, cloth, slate and straw, the palette shared with the castle construction and faction building packs. Static geometry; no rig, animation, collision or navigation data.","status":"published","url":"https://3dassets.dev/assets/medieval-siege-and-castle-defence-machicolation-course-c6b290ca","cdnUrl":"https://cdn.3dassets.dev/assets/28842/v1/model.glb","downloadUrl":"https://3dassets.dev/download/medieval-siege-and-castle-defence-machicolation-course-c6b290ca","thumbnailUrl":"https://cdn.3dassets.dev/assets/28842/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/28842/v1/poster.webp","blurhash":"UDFYx;_300xus:~p-;D%00IU?bs;Rj00IUxa","category":{"slug":"buildings","title":"Buildings & Architecture"},"tags":[{"slug":"medieval","title":"Medieval"},{"slug":"low-poly","title":"Low Poly"},{"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":13208,"triangles":240,"vertices":720,"meshes":2,"materials":2,"textures":0,"animations":[],"boundingBox":{"min":[-2,-8.893292405831588e-7,-0.4899568210774631],"max":[2,1.8200009417813279,0.9999568115407199]},"sizeMeters":[4,1.82,1.49],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Fable 5.1","downloads":0,"publishedAt":"2026-09-08T03:57:28.887Z","updatedAt":"2026-09-08T03:57:28.998Z","usage":{"threejs":"import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'\n\nconst loader = new GLTFLoader()\nloader.load('https://cdn.3dassets.dev/assets/28842/v1/model.glb', (gltf) => {\n  scene.add(gltf.scene)\n})","r3f":"import { useGLTF } from '@react-three/drei'\n\nexport function MachicolationCourseMedievalSiegeAndCastleDefence(props) {\n  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/28842/v1/model.glb')\n  return <primitive object={scene} {...props} />\n}\nuseGLTF.preload('https://cdn.3dassets.dev/assets/28842/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/28842/v1/model.glb\" alt=\"Machicolation Course (Medieval Siege and Castle Defence)\" 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/28842/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/28842/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);"}}}
