Detailed Corridor Designs in Civil 3D I

Building simple linear corridors is just the beginning – designing cul-de-sacs, intersections, and complex regions requires advanced skills. This course teaches Civil 3D users how to handle these design challenges efficiently and accurately. You’ll learn to create cul-de-sac assemblies and profiles, work with multiple baselines and assemblies, and use the Intersection Wizard to develop precise intersection surfaces and assembly sets.

This 4-hour 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 Autodesk 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.
