# Captured Object Attributes Determine details about the objects and surfaces that the framework identifies in a scan. ## Overview Each [`CapturedRoom.Object`](/documentation/RoomPlan/CapturedRoom/Object) contains attributes that the framework observes during a scan that convey details about the object. For example, an object of category [`CapturedRoom.Object.Category.chair`](/documentation/RoomPlan/CapturedRoom/Object/Category-swift.enum/chair) may contain the attributes [`ChairType.stool`](/documentation/RoomPlan/ChairType/stool) and [`ChairLegType.star`](/documentation/RoomPlan/ChairLegType/star), which describes the framework’s observations of the chair during the scan. An object exposes these details through its [`attributes`](/documentation/RoomPlan/CapturedRoom/Object/attributes) array. By reading the attribute information the framework sets on objects, your app can provide more informed utility with a scanned room, such as: - A filtered list of product selections in a furniture catalog that matches just the categories and attributes of the present objects in the room. - A more accurate visual representation, for example when rendering a virtual reality experience, by substituting the default object bounding boxes with detailed 3D models that your app chooses. > Tip: If you export a scan result to USDZ, for example, with ``doc://com.apple.RoomPlan/documentation/RoomPlan/CapturedRoom/export(to:metadataURL:modelProvider:exportOptions:)``, objects output as bounding boxes. To substitute the boxes with detailed 3D models based on object attributes, see ``doc://com.apple.RoomPlan/documentation/RoomPlan/CapturedRoom/ModelProvider``. ## Topics ### Accessing object details [`protocol CapturedRoomAttribute`](/documentation/RoomPlan/CapturedRoomAttribute) Details about an object in the room that the framework observes during a scan.
