soffietti in pvc

[rf.infissi@libero.it]

I should make pvc bellows as in figure:
must be compressed and excreted in a set.

I thought I'd use the act like the spring.

Someone's ever found himself with these bellows and he has some advice to give me kindly.

If you really want them to be precise, it's crazy stuff and lose us unnecessary resources in opening and reviewing together.. . .
the only thing you could do is create a part with a rectangular section (or circular) with an adaptive sweep path (which can be a line or a spline, but with the spline I wish you... you may incur in nonsensical display cases) at the ends of which you create two geometry points (the yellow ones as external commands) that you will use to bind together.
then to make it "real look" you create an ad hoc "top" texture that you will apply to the external surface of the sweep....

I still wish you luck

also because it is only a graphic vezzo, which you mechanically do not need anything.

First of all I thank you for the answer, I try and hope well.
However it seems to me a simple but effective solution, we only hope that graphically it can go.
Thanks again for availability
