## Main Question or Discussion Point

I was wondering if anyone had a good method for creating an equation from a set of coordinates. Let's say I have a vase (hourglass shaped). I have x,y coordinates that map the outline of the shape to about a 0.05" tolerance. Is there some mathmatical process that I can use to, in effect "save" this curve in an equation. I tried regression, but the shape isn't exact and I am aware that there could be many equations that could potentialy follow those points.

There must be some way to do it.

Thanks
