Hello,
in this case i would agree tp Franklin's opinion regarding using two ring
instead of creating a new primitive because if we create a new primitive
section for this you will have very big number of possible combinations
(ring 1 +ring 2, ring 1 + ring 2 + ring 3) etc.
I wouldn't agree if lets say i had to use always 4 quarter ring primitives
to create a full ring.
Play well
