# init(fileAt:)

Creates an object representing the 3D content that will be previewed in AR Quick Look.

```
init(fileAt url: URL)
```

## Parameters

`url`

A file URL to 3D content file (e.g. usdz).

## Return Value

The preview object to display in AR Quick Look.

## Discussion\discussion This object will be previewed in AR Quick Look using the default
behavior:

- Start in Object mode without camera passthrough
- Display the Share button for 3D content sharing
- Allow scaling content in both Object and AR mode

This is a promise to the ARQuickLookPreviewItem class that the URL points to a 3D content file. This class does not deal with the file’s existence or content, and leaves it up to QuickLook to handle and process the URL.
