Hi James,

Thank you for your reply I am using sqrt(a-pow(sqrt(b),2))*c to feed into "Z" input of the point node now. however, I still don't get your result!

No need to mention I changed cone specifications to what you suggested there appears only one cone!

My question is that I see your "shiftDublicate" node says "numArray" while mine says "In" what am I doing wrong?
