With the Center command, you can define the center of the current view of a model. To define the center, drag the cursor over the model. A sphere is displayed in addition to the cursor. The sphere indicates that the point below the cursor in the model is 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 an icon indicating that the operation cannot be performed (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.
