Chapter 9
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.
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
