Choose a (or make a new) surface style that has elevations turned on in the plan view (surface style -> display tab -> elevations -> light bulb on). Assign that style to the surface (can use properties panorama to assign the style or go to surface properties). After that, click on the surface, right click and go to surface properties. Go to the analysis tab. On the pull down, choose elevation. Enter the number of elevations you want to shade. Click the down button to show the elevations in the window below. Edit the value of the elevations you want to shade. Click apply. That should do it.

You can use one of the preconfigured Elevation Band styles. See the help system for topics related to Surface Analysis to learn more about the settings.

Go into your Surface Style, on the display tab, use 'View Direction' pulldown and go to 'Model'. Ensure 'Elevations' are on. Turn the rest of the display components off. Now you should be able to use Object Viewer to view the elevations in 3D (Right click on the Surface and you can choose Object Viewer). Within Object Viewer choose a visual style such as Realistic.

If you don't want to use object viewer, you could also go to the View tab within the Ribbon, choose an Isometric View from the list there and change the visual style to Realistic.
