# height

The extent of the box along its y-axis. Animatable.

## Declaration

```swift
var height: CGFloat { get set }
```

## Discussion

Discussion The box is centered in its local coordinate system. For example, a box of height 10.0 extends from -5.0 to 5.0 along the y-axis. The default width is 1.0. A height of zero or less creates an empty geometry. You can animate changes to this property’s value. See Animating SceneKit Content.
