I did it as Dean suggested.
> First created a 3D Spline that was half of the Infinity symbol (the Coral colored spline, in the pic below)
> Then created a circle on one endpoint of that spline. Used Graphic on Path, Nearest on Graphic snapping in Plan View, to-- bye eyeballing it*-- evenly distribute the circles on that spline. (The green circles, in the pic) (I liked the way the circles stayed "normal" to the spline, using the Graphic on Path command)
> Individually selected and resized each of the circles, using some math to determine what size each one should be so that when I went to Loft, the eventual Loft would pretty much uniformly taper down.
> Copied the Spline and Circles to the corresponding other side (the half that is on the left-- blue Spline, black Circles)
> Used the Loft Tool to loft, selecting all the Circles for the loft, starting and ending with the one at the top-left in the pic (where there is a bit of a sharp point)
Thanks for the exercise.
* "...Nearest on Graphic snapping in Plan View, to-- bye eyeballing it...": I should have used a Divide Snap, first setting the Divide Snap to about 10-- I think.
