Free roam
Choose Free roam, then drag on the model to look around from the camera. WASD moves, Q / E lowers or lifts, and Shift moves faster.

Pan and move closer
Right-drag to move sideways or vertically. Scroll to fly forward or back. Double-click a detail to move closer.

Walk
Move through rooms at floor height with walls and stairs respected. Walk up or down the stairs to change floors. Use Top floor or Ground floor for an explicit shortcut.

Edit objects
Click Edit, select an object, then drag Move or Resize handles. Delete removes it; Undo and Redo restore edits. Changes save in this browser. Done editing returns to normal door controls.

Explore inside
Use the floor and roof controls to look inside. Click doors, light switches or toilet lids to operate them.

Lighting
Use each room’s wall switch or choose it from the Lighting menu to set colour and brightness.
