Chapter 9Basic Corridors

The corridor object is a three-dimensional 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, but they aren't limited to just road travel ways. Corridors can be used to model many linear designs. This chapter focuses on building several simple corridors that can be used to model and design roads, channels, and trenches.

In this chapter, you will learn to:

  • Build a single baseline corridor from an alignment, profile, and assembly.
  • Use targets to add lane widening.
  • Create a corridor surface.
  • Add an automatic boundary to a corridor surface. ...
