How to do animation makes many small squares move in circle (each square form a layer)?

I also saw graphics object move in 3D circle with zoom in / zoom out (each graphics form a layer), do people do it frame by frame using hand?

are there chance people is using 3rd party software to do the animation? I heard swift3D can do 3D stuff then export to flash frame by frame automatically

also take a look at the animation of the circle (make from 7 square, each square move in circle perfectly) is there any third party tool people using and then export to flash (is it very possible?)

otherwise, it would be too hard to do it frame by frame using hand isn't it? (if you take a look at the Timeline) everything of the 7 box is do my hand!
