Hi Yenmonger - the booleans will probably have a hard time at the very tip where there are kind of many tiny fragments overlapping over top of each other.

What I would recommend would be to draw a small sphere at the top and bottom poles, then select your longitudinal sections and use boolean difference and subtract the 2 small spheres away from them.

This will prevent them from all intersecting in a confusing way at the top and bottom areas, and should allow for a cleaner boolean with the main body.

Those "pole spheres" don't have to be very large, just big enough to stop all those lines from running right over top of each other.

If that doesn't work or doesn't make sense, could you please post the .3dm model file of what you've got so far? It is always easier to make suggestions when the actual model file is available to work with.
