It is, thanks, I did something like that by hiding the curve at first with a

rectangle and rotating the rectangle in order to cover less and less of the

quarter of the circle, but I could not use this approach when drawing

"irregular" curves. In the end I took the advice Taylor suggested. I'm using

the curve I want to draw as a motion guide for an object that "draws" the

path. I duplicate the path on another layer, hide the motion guide and then

insert keyframes between the first and last frame of the animation. Then

look for the intersection point between the object that "draws" the curve

and the curve itself and on each frame I delete everything after the point

at which the moving object has arrived. It looks like it tweens, but

actually it is a series of keyframes that does the job. Lots of works but

looks ok in the end.
