pattern on projected 3d curve

[cikho]

Hello, everyone!
I need to shape a flexible corrugated tube similar to this
this tube is internal to an assembly and is "contorce" in space (pass the term) with a series of curves. I was thinking of making it with a sweep, using a sketch projected on a surface and reuse the sketch projected to realize the pattern of corrugation. .
only that wf4 does not make me select the sketch projected for the pattern..
Is there an alternative way to achieve it?
Thanks

I edited the message, as from regulation, the images should be handled as attachments and not as you had done.

for your question:
it is preferable to indicate the corrugation symbolically, what you want to do is very heavy for any cad.
generally in these cases it is better to use the reference curves for points.

ops, I'm sorry for the image, I thought you'd put it in the annex, mea culpa!
However at this point I would prefer the symbolic method too.. but there is a way to indicate it in 3d or then I place it in distinct base on the exploded (ignorance, I know )
