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.
