Displaying and Analyzing Surfaces
Because you're working with surface objects in Civil 3D, you can do much more
than simply show contours. Civil 3D surfaces can help you tell many different
stories about the shape of the land and how water will flow across it. They are
able to do this through multiple types of analyses as well as the ability for styles
to display analysis results in nearly any way you wish. With these tools at your
disposal, you can study the terrain thoroughly and make smart choices about
the direction of your design early in the process.

Analyzing Elevation
Elevation analysis allows you to delineate any number of elevation ranges and
then graphically distinguish the different ranges by color. This is a useful tool
in many instances, especially when you're working with someone who doesn't
know how to read contours.
Exercise 4.6: Analyze Elevation
In this exercise, you'll perform an elevation analysis on a surface in your drawing.
