# Dolled Rail Section (Racecourse and Parade Ring)

An 8 m dolled rail section: the same posts with the running line carried 0.9 m out on angled brackets, which is how ground staff move the racing line off worn turf.

## About

An 8 m dolled rail section: the same posts with the running line carried 0.9 m out on angled brackets, which is how ground staff move the racing line off worn turf. Dimensions 8.12 by 1.16 by 0.99 m (X by Y by Z). Metre units, +Y up, +Z front, origin on the footprint at ground level. Connectors: start (rail) at (-4.00, 0.00, 0.00) facing (-1, 0, 0); end (rail) at (4.00, 0.00, 0.00) facing (1, 0, 0). The ports stay on the post line, so a dolled section drops into a straight rail run and the running line steps out at it. Turf course palette: mown and unmown green, rail white, timber, birch brown, steel, charcoal, course green, red, yellow, hardcore grey and glass. No name, number, price or maker mark appears anywhere on this model, and it carries no creature. Static geometry; no rig, animation, collision or navigation data. Functional variant of running-rail-run, with its difference modelled rather than animated.

## Use with three.js

```js
import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'

const loader = new GLTFLoader()
loader.load('https://cdn.3dassets.dev/assets/38596/v1/model.glb', (gltf) => {
  scene.add(gltf.scene)
})
```

## React Three Fiber

```jsx
import { useGLTF } from '@react-three/drei'

export function DolledRailSectionRacecourseAndParadeRing(props) {
  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/38596/v1/model.glb')
  return <primitive object={scene} {...props} />
}
useGLTF.preload('https://cdn.3dassets.dev/assets/38596/v1/model.glb')
```

## Blender

```python
# Blender 4.x: File > Import > glTF 2.0, or from the Python console after downloading the file.
import bpy
bpy.ops.import_scene.gltf(filepath='model.glb')  # from https://cdn.3dassets.dev/assets/38596/v1/model.glb
# Metres and +Y up are converted to Blender's Z-up scene automatically.
```

## Godot

```gdscript
# Godot 4: copy model.glb into res://models/ and the editor imports it as a scene.
var packed := load("res://models/model.glb") as PackedScene
var model := packed.instantiate()
add_child(model)
```

## Unity

```csharp
// Unity: import model.glb with glTFast (Package Manager: com.unity.cloud.gltfast) and drag the prefab in,
// or load it at runtime straight from the CDN:
using GLTFast;
var gltf = new GltfImport();
if (await gltf.Load("https://cdn.3dassets.dev/assets/38596/v1/model.glb")) await gltf.InstantiateMainSceneAsync(transform);
```
