Lofting offset curves

Hi! 

Im trying to offset a set of curves which have been offset to a smaller scale as they rise in the z vector. I would like to loft them, but I have no way of doing this as one would in Rhino (where you click on all the lines in order and create a loft. Right now I have a lofted between the first and last curve, but the loft does not pass through the curves in between, which complicates my surface. Is there anyway to join them in one step?

Thanks a whole lot! :)

What about connecting directly the output of Scale to the input of Loft ?

The Loft component only works with Open OR closed splines.

When your offset makes the splines too small, they turn in on themselves and either self-intersect or simply open. (I did not look closely)

I tested for Closed curves, and used that boolean pattern to cull the open curves before the loft.
