Needed advice on minus-sing off multiple uneven the extrusion holes from the solid

hello mcneel community

I am struggling to cut out/minus off the extrusion holes from the solid (circular shape). I tried extruding the planar curve with straight, but it does not have a cap or becomes a solid. Anyone knows how should I extrude the holes as a solid as they are projected on the uneven surface? Or if there are any other method for me to create the holes on the solid?

Appreciate if anyone could help out! Thank you. :grinning:

Hello - make sure Solid=Yes on the ExtrudeCrv command line - does that do it?
