# supportedCombinations

An array of supported attributes that differs by category.

```
var supportedCombinations: [[any CapturedRoomAttribute]] { get }
```

## Discussion

The framework defines the contents of this array. Only compatible attributes can pair up in association with a 3D model, for example, with the [`CapturedRoom.ModelProvider`](/documentation/RoomPlan/CapturedRoom/ModelProvider) function [`setModelFileURL(_:for:)`](/documentation/RoomPlan/CapturedRoom/ModelProvider/setModelFileURL(_:for:)-8xio). These [`CapturedRoom.ModelProvider`](/documentation/RoomPlan/CapturedRoom/ModelProvider) functions for `setModelFileURL` and `modelFileURL` throw [`CapturedRoom.ModelProvider.Error.attributeCombinationNotSupported`](/documentation/RoomPlan/CapturedRoom/ModelProvider/Error/attributeCombinationNotSupported) if no object category supports all of the attributes in the arguments to their call.
