Hi Pilou.

@You : "So with Flow function! :)"

Kepp in mind that for this situation, if you don't use the "Rigid" option of the Flow command, the resulting surfaces will be deformed.
That is they will not have the same topology of the input objects and you will have a resulting objects with much more control points.

See you.

P.S. Maybe, besides NodeEditor, it should be some other different ways to perform a a REAL distribution of a bunch of objects along a defined curve.
If remember correctly, the Max's VSeed + VCLone scripts will do the job.

I have to try.

See you.
