Revit Walk mode in 3D Camera View
Did you select the right steering wheel (there are différent ones for walking through, navigating around an object, ...)?
They are available actionning the little menu under the steering wheel button.
On the other hand, a walk through is made using a path and cameras and controled via the path handles? ( 3D view > walk through).
Do you want to simply navigate through your project as if you were walking through it?
