I was trying to reproduce a training procedure for making an animation. The
procedure starts by adding a symbol to a frame, reproduces the frame and
changes the symbol a bit (making it a little narrower), and repeats that
process in a series of frames. When I tried this, any change I made to my
symbol (rotating it) for some reason made the same change in all of my onion
frames. So the frames are connected in some way, and my shape is actually the
same object in all of them. How do I make independent copies of the shape so
that I can make it change in each frame?
