# init(string:extrusionDepth:)

Creates a text geometry from a specified string, extruded with a specified depth.

## Declaration

```swift
convenience init(string: Any?, extrusionDepth: CGFloat)
```

## Parameters

- `string`: An doc://com.apple.documentation/documentation/Foundation/NSString or doc://com.apple.documentation/documentation/Foundation/NSAttributedString object containing text from which to create the geometry.
- `extrusionDepth`: The extent of the text geometry in the Z dimension of its local coordinate space. Specify a depth of 0.0 to create 2D text confined to a plane.

## Return Value

Return Value A new text geometry.

## Discussion

Discussion In the local coordinate system of the text geometry, the origin corresponds to the lower left corner of the text’s layout rectangle, with the text extending in the x- and y-axis dimensions. (SceneKit computes a layout rectangle automatically, or you can specify one using the containerFrame property.) The geometry is centered along its z-axis. For example, if its extrusionDepth property is 1.0, the geometry extends from -0.5 to 0.5 along the z-axis. An extrusion depth of zero creates a flat, one-sided shape—the geometry is confined to the plane whose z-coordinate is 0.0, and viewable only from its front unless its material’s isDoubleSided property is true.
