Site Grading for Civil 3D I

Grading a site accurately in Civil 3D can be challenging without a clear approach. This course teaches designers how to create realistic site grading using feature lines and grading objects. You’ll learn to build, edit, and manipulate feature lines, develop grading objects, and generate dynamic surfaces for practical, professional site designs—including detention basins and daylighted areas.

This live online series offers 2 four-hour courses. You can take both courses or just the one that meets your needs. Each separate 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.
