Chapter 11. Easy Does It: Basic Corridors

The corridor object is a three-dimensional road model that combines the horizontal geometry of an alignment, the vertical geometry of a profile, and the cross-sectional geometry of an assembly.

Corridors range from extremely simple roads to complicated highways and interchanges. This chapter focuses on building several simple corridors that can be used to model and design roads, channels, and trenches.

By the end of this chapter, you'll learn to:

  • Build a single baseline corridor from an alignment, profile, and assembly

  • Create a corridor surface

  • Add an automatic boundary to a corridor surface

Understanding Corridors

In its simplest form, a corridor is a three-dimensional combination of an alignment, a profile, ...
