#declare Radius = 0.2;
#declare Circle = function {sqrt (x*x + y*y)}

/ function before repetition
 #local F =
 function {
  pattern {
   function{
    //PF(0, sqrt(x*x+pow(max(y, 0), 2)), 0)
    PF(0, max (sqrt(x*x+pow(max(y, 0), 2)), Circle (x, y, z) - Radius), 0)
   }
   rotate -z*180/N
   translate y*Scale
  }
 }


Gives me an N-sided hole in the center.
Not sure how to get it to be an actual circle....
