To Invoke the Link for a Selected Roundabout

There are two ways to invoke the link, the ‘official’ way and a more convenient quicker way. First the ‘official’ way:

1. Select a roundabout with at least two arms.
   Note: The link may not work correctly for fewer than two arms.
2. Click the Roundabout tabRoundabout Properties.
3. Select the ARCADY Analysis.
4. Select the Enable ARCADY Link checkbox. This action also enables the global switch if it is disabled.
5. Select the data items that wish to see in the HUD.
6. Click Apply and close the Roundabout Properties dialog.
7. Autodesk Civil 3D 2025 should start ARCADY, if it is not already running, and attempt to connect to it. If it succeeds, the selected data is displayed in the HUD’s.
Note: The connection process may take a few seconds, especially if Autodesk Civil 3D 2025 has to start ARCADY.

Now the slightly quicker way:

• Select a roundabout.
• Click the Refresh Data button on the Roundabouts toolbar or ribbon.
• Depending on the state of your system, you may be prompted first to confirm that you want to switch on the ARCADY Link, and then that you want to enable the link on the selected roundabout.
• If you confirm both prompts, ARCADY starts (if not already running), Autodesk Civil 3D 2025 attempts to connect and within a few seconds, you should see the data in the HUD’s.
