ARCADY 8 or above, available from TRL, can communicate with AutoCAD Civil 3D 2017 Roundabouts.
The ARCADY-AutoCAD Civil 3D 2017 link is a two way dynamic data link that allows AutoCAD Civil 3D 2017 Roundabouts users to view ARCADY results directly in AutoCAD Civil 3D 2017. The link operates in real time with AutoCAD Civil 3D 2017 passing geometric data to ARCADY which in turn passes back the roundabout performance values which are then displayed on the roundabout in AutoCAD Civil 3D 2017.
To use the link you will need:
The link must be enabled from both applications to work.
In AutoCAD Civil 3D 2017, the link is controlled by two switches, one global in system settings, and the other per roundabout accessed from the Roundabout Properties dialog. This allows you to enable the link for selected roundabouts and provides a convenient means of switching the link on and off for all roundabouts.
Refer to the ARCADY documentation for how to register and enable the link in ARCADY.
