# init(width:height:length:chamferRadius:)

Creates a box geometry with the specified width, height, length, and chamfer radius.

## Declaration

```swift
convenience init(width: CGFloat, height: CGFloat, length: CGFloat, chamferRadius: CGFloat)
```

## Parameters

- `width`: The width of the box along the x-axis of its local coordinate space.
- `height`: The height of the box along the y-axis of its local coordinate space.
- `length`: The length of the box along the z-axis of its local coordinate space.
- `chamferRadius`: The radius of curvature for the edges and corners of the box.

## Return Value

Return Value A new box geometry.

## Discussion

Discussion The box is centered in its local coordinate system. For example, if you create a box whose width, height and length are all 10.0, it extends from -5.0 to 5.0 along in each of the x-, y-, and z-axes.
