Does anyone know the difference between polyline and arc in waypoints 2.0 (other than no automatic camera action in arc)?
The polyline route type will make the aircraft fly a straight line from waypoint to waypoint. Arc will make the aircraft fly a smooth curved path as it arrives and leaves a waypoint.

Thanks, I have been looking for something like this that explains all the details.
