This tutorial demonstrates how to create a corridor with a transition lane. The tutorial uses some of the subassemblies that are shipped with AutoCAD Civil 3D to create an assembly. Then, you create a roadway where the travel lane widths and slopes are controlled by offset alignments, profiles, polylines, and feature lines.
For more information, see the AutoCAD Civil 3D Help topic Assemblies and Subassemblies.
Topics in this section
- Exercise 1: Creating an Assembly with a Transition Lane
In this exercise, you will create a corridor assembly with transitions.
- Exercise 2: Creating a Corridor with a Transition Lane
In this exercise, you will create a corridor using the assembly created in the last exercise. You will target the width and elevation of the right lane edge to a right alignment and profile, and the left lane edge to a polyline and a feature line.
