1. Pick the size of part you want to use. Save that part as “A”
2. Go into the BP. Rotate it 10 degrees, and import it. Stacking the pieces directly on top of eachother.
3 continue doing this for 20, 30, 40, (or any increments you’d like), up to 80 degrees. All stacked like so. Then duplicate it (in case you mess up)
(You may consider saving this as a template to make future circles.
4. Take one of the stacks, and spread the pieces out. Be careful not to snap them into anything.
5. Decide what radius you want your circle to be. Then copy each piece enough to make the stacks that high, keeping your original piece on the bottom.
(I chose to use 8 as a radius)
6. When you have all your stacks, stack them on top of eachother so that the bottom pieces are positioned the same as they were before you spread them out.
I put the rest of the instructions on this screenshot to save time and space.
Good luck
