hi, have managed reflect objects cannot manage reflect 1 object across artboard show on opposite side. if see image below, reflect horizontal stripe @ top of design , make appear @ bottom of artboard finishes design. of work requires 1 quarter of design created, reflect across , reflect down useful piece of knowledge have if help

 

onwards,

 

if understand in right way, may:

 

1) create first quarter (the top left presumed),

2) create (possibly nostroke/nofill) circle centre @ final centre, large enough extend past artwork,

3) group 1) , 2) , object>transform>reflect horizontally copy,

4) select , object>transform>rotate or reflect vertically copy.

 

use rotate in 4) bottom midlle part shown, use reflect mirror top one.

 

you may delete circles when done (or leave them nostroke/nofill further editability).
