You can use the new ViewCube tool and NavBar, or the View Panel to control your view, or you can choose to use neither.
Of special interest are the following tools:
Clicking the Look at icon centers the view and zooms in on the selected objects (or all objects if nothing is picked).
Checking Plane view lets you tumble about the currently active construction plane (that is, the construction plane is used as the ground plane).
As you work on a model, you typically change the camera view back and forth between two or more areas of interest. The view panel lets you “bookmark” these views of the model by saving them as variants. You can return to those views by clicking the name of the variant.
The Viewing Panel does not appear when I hold + ?
