Designing a roundabout in Civil 3D may seem straightforward, but once you get into alignments, profiles, corridors, and intersections, it quickly becomes a complex task.
In this detailed tutorial, instructor Paul takes you through every step of creating a complete roundabout in Civil 3D, from building the base layout to handling grading, corridor modeling, and intersection design.
You’ll learn how to set up smooth circular alignments, manage complex intersections with precision, and keep your corridor clean and ready for revisions.
Whether you’re designing your very first roundabout or looking to sharpen your Civil 3D workflow, this video will guide you through it with clear, real-time demonstrations.
Jump in, follow along, and master the art of roundabout design in Civil 3D.
