you can define animations using curves if you use PathAnimator
but atm we cannot display curves like in 3.x

one workaround would be to calculate the points on curve and draw each segments 
from points to points.
you can find the code for this in extrusions.utils.PathUtils

public static function getSegmentPoints(pStart:Vector3D, pControl:Vector3D, 
pEnd:Vector3D, n:uint, last:Boolean):Vector.<Vector3D>
