You may enter non-geometric data in ARCADY at any time.
Values that are controlled by AutoCAD Civil 3D 2017 are read-only, any others may be changed. To update the AutoCAD Civil 3D 2017 display for changes made to ARCADY data, you must synchronise the data by clicking the Refresh Data Link button in AutoCAD Civil 3D 2017.
Important: Not all items that you can add in AutoCAD Civil 3D 2017 are passed to ARCADY. For example, you can add pedestrian crossings in AutoCAD Civil 3D 2017 but they are not sent to ARCADY. Likewise, although AutoCAD Civil 3D 2017 models mini-roundabouts, ARCADY does not yet process this data when sent from AutoCAD Civil 3D 2017.
