I have a sphere and I want to make some cylindrical cavities on it's surface, which are tangent to the sphere's surface The cylinders wich which I should make the boolean difference should be disposed as a sea urchin, i suppose: with the bottom faces of the cylinders being on the same origin and the top faces spreading out radially.
Here are some images to give a better idea of what I should do:
This is a "flattened" version of what I want to acieve
How do I do the same thing on a sphere?
I need to get to the point where i get something like this but with the cylinders going all around the sphere orbiting around its Z-axis
Thanks in advance :D
Edit: Is there a versatile way of doing so on objects which have an elliptical/irregular shape?
