Using Hillshading and Vertical Exaggeration
Hillshading adds shading to 3D surface layers by casting the sun's light across
a surface from the direction and angle you specify.
Hillshading produces a more realistic image and helps you better understand
the magnitude and relationships of the various elevation changes (that is, the
bumps and valleys) on the surface.

Hillshading is on by default for each surface layer in your map, however, you
can choose to turn it off (or on again) at any time on a per layer basis.
You can change the sun settings that AutoCAD Map 3D uses to apply
hillshading. These settings are used throughout AutoCAD Map 3D and are
applied to all surface layers that have hillshading turned on.
You can also control the appearance of the elevation changes, making them
appear more or less extreme, using the vertical exaggeration setting. Increasing
the vertical exaggeration intensifies the hillshading, making the elevation
changes appear more extreme. The vertical exaggeration setting is applied to
all surfaces you are viewing.
In addition to these settings, you can use AutoCAD commands to change the
appearance of surfaces. For example, you can use the VISUALSTYLES command
to display the surface in 3D Wireframe, 3D Hidden, Realistic, and Conceptual.
