# LowLevelMeshPart

An object that describes a range of primitives to draw from a mesh resource.

## Declaration

```swift
final class LowLevelMeshPart
```

## Overview

Overview A mesh part selects a contiguous range of indices from the mesh’s index buffer and associates them with a primitive type, winding order, and bounding volume.

## Topics
