Click the View | Trackball command
or click the 
button to rotate the view
in the Viewer window.
This command uses a virtual trackball interface, which can be thought
of as an invisible sphere centered in the middle of the Viewer
window. You can rotate the sphere and graphics in the window by dragging
the mouse on this invisible sphere.
Move the mouse cursor to the Viewer window. Hold down the left mouse button and drag the mouse to rotate the view. To keep the view stationary, stop moving the mouse prior to releasing the left mouse button.
To spin the view, release the left mouse button prior to stopping the mouse. The faster the mouse is moved, the faster the graphics spin. Graphics are rotated in the direction the mouse is moving at the time the mouse button is released. Click the mouse in the Viewer window without moving it to stop the spinning.
You can add a dragger to some modules for use in rotating the associated geometry.
The view can be changed in a number of ways while in trackball mode. Hold down the CTRL key and the left mouse button and then move the mouse up or down to zoom the view in or out. Hold down the SHIFT key and the left mouse button and then move the mouse around to pan the view. Finally, you can scroll the mouse wheel up or down to zoom the view in or out. The mouse controls can be customized on the Mouse page of the Tools | Options dialog.
Changing the view using the trackball cannot be undone.
