## Start

Drag the sparse Cube or Tree onto the drop zone.

Once added, to see a copy of the Cube or Tree used to create the virtual variable, simply right click on the item in the drop panel and select **View a Copy**

Tick the **Create URN Snapshot** box to record the exact records found at this time so it can be recreated after a refresh of the data if needed.
