I would like to create an animation to open circumference of a circle as a straight line exactly. I am currently learning After Effects and i have some idea about it but i could not do it.

It is very important to me. Can anyone help me to do it?

  • I'd be interested in knowing this too.. Initially I thought you could turn a circle path into a bezier, but this doesn't work as the bezier is joined up, and also the paths are "stretchy". I'm guessing you need to do it as an expression somehow, maybe with beams? – tomh Feb 21 at 9:16


Here, Rick Gerard gives a few suggestions how you could do it.

I guess best way would be to make a line and bend it like a circle, zoom really far in and put the end points near each other, but don't connect them
