   Hey @Trial-In-Error,
   Yeah it is supported in an indirect way, but I should probably document the intention better though.

   polyRoundExtrude supports negative fillets, you have to then put on your normal OpenSCAD thinking hat and use difference with another polyRound like so.
   

   radiiPoints=[[10,0,10],[26,20,1.1],[8,20,10],[0,7,0.3],[5,3,0.1],[-4,0,1]];
   radiiPointsNegative=[[11,10,0],[15,15,1.1],[11,15,1.1]];
   negativeFilletsForHole=-1.5;
   extrudeHeight=2;
   difference(){
       polyRoundExtrude(radiiPoints,extrudeHeight,0.5,0.5,fn=8);
       translate([0,0,-0.005])polyRoundExtrude(radiiPointsNegative,extrudeHeight+0.01,negativeFilletsForHole,negativeFilletsForHole,fn=8);
   }

   A big assumption under the hood with polyround is that you'll be making a ring/closed-loop. It might be possible to take that assumption out of the code, but it's pretty old code. if I were to do a re-write I would change a great many things

   Does that help?
