When a model first opens, you'll see the full-size minimap. Close it to start moving around with the controls below. You can get around using the on-screen joysticks, touch gestures, or both.
Joysticks and buttons
Move (left joystick): Push it to walk forward, backward, and side to side.
Look (right joystick): Push it to turn and look up or down.
Up and down arrows: Raise or lower your position. Use these to reach upper floors, get up to ceiling equipment, or drop back down to the ground.
Back arrow: Tap it in the top left to close the model and go back to your model list.
Touch gestures
You can also move by touching the model directly:
Pinch open to fly forward.
Pinch close to fly backward.
Drag with two fingers to slide left, right, up, or down without turning.
Gestures are handy for small adjustments, like lining yourself up with a wall or getting closer to a piece of equipment.
