Loft of several curves

Hello all,
I’m trying to make an array of columns, each one with 3 curves (bottom, middle, top) which the middle one has random sizes (scales). I’ve created the curves but I don’t know how to re-sort them correctly to loft.
When I loft them GH ties the bottom and top curves altogether, then the middle ones.
Any help ? (9.8 KB)

You didn’t internalized your curve parameter. It’s empty.
See bellow link especially no. 3

Sorry, I didn’t know it could be possible… shame! (10.4 KB)

There are other ways to do this… (20.3 KB)

Thank you very much ! I’ll take a look on these ways.
