Intelligent Road Design in Civil 3D II

Corridor modeling is often the most challenging part of Civil 3D, but mastering it is essential for accurate road design. This course focuses on creating and editing corridors, managing regions, and applying target and slope controls to develop precise, easy-to-update roadway models. You’ll also learn to generate and control corridor surfaces and sections for professional, real-world road 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 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.
