If you navigate in your model (without switching to another views in view map or changing perspective to isometric) - you can go back to original view by using "previous zoom" button - next to zoom button in the left lower part of screen.
You also can save your preferred view into view map - having set of views than you can easily navigate between them. You also can set cameras, calling them, for example, apartment 1, apartment 2, exterior views, ground floor and similar. When you save camera set into view map, you can rename cameras. Then you are getting entry called "Apartment 1" with following cameras, named by rooms: "bathroom, kitchen, corridor".
It's a very good feature - to use cameras, because after you can export your cameras into BIMx and they will appear there too, as gallery entries.
