I have never seen this before, searched the forum but didn't really know what to look for.  Im using 2010 sp3.1.  I did an extruded cut of a rectangle with rounded corners.  After the cut the radiused corners' edges become a series of segments.  I have redrawn it and recut several times.  Same thing.  And it is all the corners in this cut, but no other features have this problem.

Anyone know why?

Thanks
