Creating spikes in different directions

Hey all,

I am trying to create a cactus-like geometry for a class assignment. I created curves using Metaball and I want to place cones throughout these curves (which will resemble cactus spikes). how can I control the directions of these cones so that they will all face out of the cactus in a logical direction?

I attached the gh file - right now most of the cones are not in the direction I’m interested in . thanks in advance for all the help! (14.4 KB)

Exactly! thank you so much
