Control Navigation Realism
You can use collision, gravity, and crouching with the Walk tool. This allows you, for example, to walk up and
down stairs and walk under low objects.
You can also use the third person view with SteeringWheels to enhance your navigation experience. However,
the avatar is only shown when you use the Walk tool, and the Pan tool to prevent cluttering of the screen.
Center Tool
With the Center tool, you can define the center of the current view of a model. To define the center, you drag
the cursor over your model. A sphere is displayed in addition to the cursor. The sphere indicates that the point
below the cursor in the model will be the center of the current view when you release the mouse button, the
model is centered on the sphere.
NOTE If a center point on a model cannot be identified, then a prohibited icon (a circle with a diagonal line) is displayed
instead of the sphere.
The point defined by the Center tool provides a focal point for the Zoom tool and a pivot point for the Orbit
tool.
NOTE If you want to zoom from the Full Navigation wheels from your defined center point, hold down CTRL before
zooming.
