AutoCAD 2010 :: Polar Array Function

I have drawn a bar counter in 3d which has a top rectangular shape with curved corners. The front of the bar has 100mm wide wooden fascia panels and they need to follow the line of the bar. I am using the Polar Array function which works great except I cant seem to get the panels to follow the curves/arcs around the corners, but they sit neatly on all the straight edges of the bar. So in other words the panels are straight and lined up on the straight parts of the bar but the panels stay at 90 degrees instead of following the curved areas of the bar.
