Thank you very much - that's what I was looking for.
I'm not very firm with matrix transformation yet (anymore), so it is
possible to get the global position of the center of an object deformed on a
curve?. Of course the center of an object wich is deformed rests in the
middle of the world space - but maybe it is possible to compute the deformed
position of the center.

you have to multiply by the global transformation of the object.
jscript:
var geo = obj.activeprimitive.geometry;
var pnts = geo.points;
var transform = obj.kinematics.global.transform;
var pntPos = pnts.item(index).position;
var pntPos.MulByTransformationInPlace(transform);
cheers,
