You can choose from several different wheels. Some wheels are designed for 2D navigation while other wheels are better suited for 3D navigation.
The 2D Navigation wheel is for basic navigation of 2D views.
The View Object wheels are used for 3D navigation. Use these wheels to view individual or groups of objects in a model.
The Tour Building wheels are for 3D navigation. Use these wheels to navigate within the interior of a model.
The Full Navigation wheels combine the 2D and 3D navigation tools found on the 2D Navigation, View Object, and Tour Building wheels into a single wheel.
