Problem with turning shape into a cone

Hey Rhino Community,

I’m new to rhino and need to do a school project where i am to design a lamp. I’ve designed this so far but my prof would like me to turn this shape into a cone and i am completely stuck. I just dont understand how i can make this lamp i have already made now into a cone like shape instead of cylindrical. Any help is appreciated !

If you want to edit what you have, CageEdit would let you do that. Taper too, it’s the same tech.

thank you so much, that worked !
