With the Center tool, you can define the center of the current view of a model. To define the center, drag the cursor over your model. A sphere (pivot point) 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 the cursor is not over the model, the center cannot be set and a prohibited cursor is displayed.
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.
