in the shape manager’s menu bar. Click the update icon to refresh the viewer every time you select another object that you want to appear in the shape viewer.
The shape viewer displays the current state of the object's shape as you modify it. This could be the currently selected shape in the shape list, the base shape, or the result of the shape weight blending at the current frame as you set the sliders on the Animate tab.
You can orbit, pan, zoom, and dolly in the viewer as you do in a user view in the viewport.
You can also select a display type from the display menu in the shape manager's menu bar, such as shaded, wireframe, etc. These are the same types of geometry displays that are available from the display menu in a viewport.
Displaying Objects in the Shape Viewer
By default, the shape viewer displays only the currently selected object whose shapes you’re modifying, but you can also display all objects in the scene in it. You can also display points and clusters on an object.
To display an object in the shape viewer
• Select any geometric object and click the Update icon in the shape manager’s menu bar. Click the update icon to refresh the viewer every time you select another object that you want to appear in the shape viewer.
• Click the lock icon 
to prevent the viewer from updating when you select another object.
To display the other objects in the scene in the shape viewer
This can be useful to do when you have reference objects that help you create shapes, such as eyeball or teeth objects that are inside a face that you are shape-animating.
• Choose View > Display All Objects from the shape manager’s menu bar.
Setting and Keeping Viewpoints in the Shape Viewer
To set the viewpoint in the shape viewer
• Select a point of view from the View menu in the shape manager’s menu bar, such as Front, Top, Right, including special Bottom, Left, Back, and Orthographic viewpoints. Orthographic allows you to orbit as in a user view, while keeping its parallel projection nature (that is, it is not perspective view)
or
• Click the X, Y, Z buttons on the shape manager’s menu bar to look at the object in the shape viewer along the X, Y, or Z axis. This is the same as viewing from the Top, Bottom, Front or Back, Left, Right views.
To memorize different viewpoints
Each memory camera (memo cam) cell 
in the shape manager’s menu bar stores a particular position, orientation, and zoom displayed in the shape viewer.
• Middle-click a memo cam cell to memorize (record) the current view. The cell turns orange.
• Press Ctrl and middle-click a filled memo cam cell to overwrite it with the current view.
• Left-click a memo cam cell to set the shape viewer to this memorized view (recall).
• Right-click a memo cam cell to delete its recorded view.
