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