A virtual training room can be created in two different ways:
Open a Digital Twin Model and then create a Virtual Training Room around it by doing as follows:
Open the relevant Digital Twin
Select: More button
Select "Create Virtual Training Room"
You should be already in the room with the ability to invite more users in to the room.
The second way is to choose to create a room and then choose the relevant model as follows:
Select "virtual room"
find and select the relevant Digital Twin
The room will load and open up immediately.
