Hello, I've tried both examples of cadquery.selectors.AreaNthSelector documentation with CQ-Editor build 219. I got an error message: " 'AreaNthSelector' is not defined. " Of course I've added `import cadquery as cq` before each example before testing. #1 `result = ( cq.Workplane("XY") .circle(5) .extrude(2) .circle(2) .extrude(10) .faces(">Z[-2]") .wires(AreaNthSelector(0)) .fillet(2) )` #2 `result = ( cq.Workplane("XY") .rect(20, 20) .extrude(10) .edges("|Z or <Z") .fillet(2) .faces(">Z") .shell(2) .faces(">Z") .wires(AreaNthSelector(-1)) .toPending() .workplane() .offset2D(-1) .extrude(1) .faces(">Z[-2]") .wires(AreaNthSelector(0)) .toPending() .workplane() .cutBlind(2) )`
