Using Hillshading and Vertical Exaggeration
Concept Procedure Quick Reference

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. For more information, refer to the AutoCAD Help.
