The vertical component of land developments is generally controlled by one of two Civil 3D features: surfaces or profiles. Surfaces cover the land-like sheets, defining vertical data as connections between points. (See Chapter 5, "Points.") Profiles handle vertical data as linear functions: a pair of station and elevation coordinates. Profiles define the model by providing the z-value, and an alignment provides the x- and y-values. In Civil 3D, profiles are tied to this relationship (with one pseudo-exception, the quick profile). In this chapter, you'll explore the profile as part of the road alignment layout and design.
