Easypose? Don't know what that is. Anyway, I want the spiral, (which in poser 9 is just a coil) to compress or expand, or be broader at the bottom than at the top, and also be able to stretch it. 

The problem with the spiral that comes with poser is while it can stretch, taper and flatten, it can't add more turns, more coils to the spiral. I need more that is why I've asked about 'welding' two spirals together.

I added another spiral to spiral 1 and then exported the two as an object, but then the new spiral.obj does not have the stretch, taper and flat morphs I want to apply.

Am I explaining it clearly enough? Just need more coils to the spiral and then need to apply the stretch, taper and flat morphs to it.
