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. |
