River Fox has 2 primary scales used to explore the environment: Dollhouse and 1:1
Dollhouse is a digital analogy to the physical scale "Marquette" models. Allowing you to assess the design from a higher level and affords a unique method of navigating the scene.
By default, River Fox scenes begin in Dollhouse for the VR User, to return to Dollhouse simply use the "Navigation" Icon on your settings bar (the lower menu, far-left icon) and select "Dollhouse".
To navigate the Dollhouse environment, simply teleport (Left-Trigger) and Rotate (Left-Thumbstick) as normal, however, you may Move, Rotate, and Scale the model in front of you by holding both Grips on the motion controllers simultaneously.
Once both grips are held, gesture back-and-forth, in-and-out, and turn your hands around (as if gripping the rim of a large plate. As you transform the model the VR UI will become invisible and a scale indicator will appear.
To reset the transform of the Dollhouse model, simply pull the Right-Trigger whilst holding both Grips.
