James,
You need the newer version...updated May 9th.

redirected,
Here is a handmade twisted tapered bend column in attached -.skp file.
- rectangle 3mx3m pulled up 30m
- top scaled by 0,5* (with +CTRL)
- top rotated 15 degrees about center (midpoint diagonal)
- sliced by 11 section planes
- edges drawn on each section plane
- outside-diagonals to create outer faces
- grouped entire structure and rotated flat (horizi=ontal)
- applied Smoove tool (in Edit mode)&(large radius / 30m) on structures center
- rotated back (vertical)
- smooted (WIP) edges and diagonals to create outer smooth surface

You group the column, choose FFD NxN, then Subdivide ought to be right there at the bottom of the dialog box.

....you forgot a small detail though ( I'am a stickler for detail, autocad days
),.......Thanks James, I realized that later. But fortunately this simple method applies to all sorts of cross sectional shapes.
(It won't happen again
)
Remus, (the link to) that horn lacks the twist. Cross sections aren't parallel -> Different approach. -

Playing around with this a bit more by manually bending a TIN. Tedious but definitely doable.
But then, of course, it is really easy, if a bit less precisely controlled, with FFD.

My bad, in my haste i didnt realise there was a twist in the shape
Looks like your all brewing up some good solutions though

Here's a version made by taking sections and realigning them to a curve. In this version the secions are normal to the curve - not sure if that's what's wanted or not.

Thanks for all the help everyone!
Not sure how to make things out of the TIN or use the ruby script, might try doing it with the tutorial on the horn first. I'll see how things go
