Green Twin has a feature to make any object or group of objects transparent or invisible. If you make architecture transparent, you will be able to see under-wall and underground installations, but you will still be able to see walls, so you can orientate in space. Also, you can make architecture invisible in order to see the details of installations.
This also comes in very handy if you want to see parts of an asset. You can go into a machine or vehicle and click on different parts to create a work order, add significant data, view history and so on.
