Radial symmetry/instance in maya

i am trying to recreate the Bionicle Voya Nui logo , the grated muzzle ring with a glass dome in the upper right corner of this image.


i can make main parts out of primitives,squashed cylinder for the base and a clipped sphere for the dome , but i am having trouble with getting the holes from the grating in round base.

to get the holes all over the base i set both the sphere and the cylinder 's radial subdevides to 32 (multiplying by 6). then i take out a 3-segment wide slice and cut the holes out with a boollean difference with cylinders ect. basically get clean holes with good edge flow. then i do a mirror and weld to make it a repeatable mesh and basically repeat the process until i remake the ring.

but i think i messed up with the welding and such because the edges between the base and dome dont line up

you see the mirror and weld didnt actually work for me. for some reason instead of placing the mirrored duplicate right next to the orignal it sent it off like several distance units to the side so i always had to pull it back in and weld it manually. but they never aligned right so with each mirror and weld the segments were squeezed and made the edges skew.

so i was hoping if there was an easier way to make segments like this line up automatically. i know in zbrush they have a radial symmetry setting for the brush so maybe maya has something similar. kind of like this :

either that or any other technique that would work as well or better. i know i can just go into zbrush and drill the hole grating in with the aforementioned radial symmetry brush but i never get stuff like that aligned right and i like the crispness polygon modeling gives t these sorts of hard surface.

i will be thankful for any help and advice but if possible can i have tutorials? will be very greatfull.

Are you not just making one section then using duplicate special to rotate around by the exact degree?

no i didnt know how to do that back then i manually mirror and welded each segment. though i did try it after learning about it but the segments still dont align at least not with the dome element. i'll try to get some screencaps in a moment. but if i do it right will all the meshes align? because i wanna get everything aligned so it'll be easier to do bollien stuff.

you can do that? will they all be uniform and not squeeze?

Made a screencap to show you.
