Building Civil 3D Corridors II

Linear corridor design is a foundational skill for any Civil 3D designer. This course guides you through creating and editing corridors, building assemblies, and controlling transitions. You’ll also learn how to design elbows and cul-de-sacs, connect multiple baselines, and develop a cohesive, accurately graded corridor for real-world roadway projects.

This course is delivered in 2 two-hour sessions. A live instructor explains the detailed functions and addresses questions as the class progresses.

​Note: Instructor will present using Autodesk Civil 3D 2026. Students who wish to follow along with instructor are encouraged to use the same version.

Prerequisite: Students should have a working knowledge of AutoCAD Civil 3D.

Recording: Registrants for a course will receive access to a recording of each session for 7 consecutive days. Access will start the next business day after the session ends.
