Interchange Design
Engineers and designers will learn how to perform common interchange design tasks faster and with improved accuracy.

Objectives

After completing this guide, you will be able to:

• Model and evaluate existing ground conditions.
• Design two new ramps for an existing project where a partial interchange system already existed.
• Create and analyze corridor models.

About AutoCAD Civil 3D in This Guide
In Civil 3D, as with most AutoCAD® applications, several possible methods exist to accomplish the same task. This guide is not intended to teach the essential features of Civil 3D, but rather how to apply software processes to particular drafting tasks. The intent is to demonstrate Civil 3D primarily as a design tool. You do not set up styles, manually edit text or labels, or perform general drafting tasks. Also, a number of design and drafting tasks would have to be completed before a final plan set would be ready for submittal.

About the Civil Engineering Processes in This Guide
This book guides you through a possible process for interchange design. The primary focus of this guide is to teach a qualified engineer or designer how Civil 3D can be used as a tool in the design solution to perform common drafting tasks more accurately and in less time. This guide is not intended to teach civil engineering principles or to recommend one engineering procedure over another. It is understood that design procedures can and do vary by region, organization, and even individual engineer. Also, due to time constraints, it is not possible to show all steps required to refine the design or to create many of the drafting components that are required for a final plan set. The features of Civil 3D used in the exercises can be applied to these tasks, enabling you to generate a plan-ready final design.
