Design and Present
By default your projects will open in Design Mode. Design mode gives you access to all the tools so that you can design your VR experience.
Switching to Present Mode just before a client presentation means that you can select or hide different tools available to the VR user. It gives you more control over what the VR user will have access to while they're inside the headset.
Click on the three dots to open the menu and from there you can choose to switch off ALL tools to give the client just a walk-through experience, turn on the measure tool if they ask about room widths or if they are confident in VR, you can give them access to the entire suite.
