In AutoCAD Civil 3D 2011, the roundabout layout tool has been added and includes several commands that enable you to create, edit, and delete roundabouts easily. Geographical or organization standards can be loaded from design standards files to help control geometry aspects of the roundabout. Details for the markings and signs located in the roundabout can also be specified.

A roundabout created using the Create Roundabout command is a 2D representation of a roundabout. Unlike intersections, there is no roundabout object but the roundabout components, including the central island, slip lanes, and approach roads, remain dynamic to the base alignment and move if the base alignment changes. This tool helps you perform quick roundabout feasibility analysis at intersection locations, which is becoming increasingly prevalent.
