Rotary module, overview

Introduction

The Rotary module allows you to create first drafts of rotaries in a comfortable and easy manner. Based on the parameters you set, the program automatically creates the basic 2D geometry and the corresponding dimensions for predefined rotary types (with 2 to 5 axes). This approach is based on the Swiss SN640... series of standards (in compliance with VSS). You can define the following parameters:

Outer and inner radius
Number and direction of axes
Width of roadway
Width of entries and exits

The finished rotary is placed in the layout and can be modified and moved.

In Switzerland, a distinction is usually made between ‘mini rotaries’ and ‘small rotaries’. Mini rotaries are defined by an outer diameter of 14 -26m and the island area in the middle can be crossed by vehicles. Small rotaries, on the other hand, are defined by an outer diameter of 26 -40m and the island area in the middle cannot be crossed by vehicles.
You can use this module to create small rotaries with an outer diameter of 24.5 -45m.
