I was thinking of sharing some variations of Rampas' flex tube in Marketplace, but then I figured fairly easy way of making them.
Here is a speedy tutorial from start to finish - everything you need to make one yourself in Blender and animate in iClone.
Physics ini file is attached.

Thank you for this turorial 4u2ges.
I am trying to follow it and it seems i could keep up up to some point.
But when you say "Select loop vertices" it looks different here.
I cannot select the vertices like your are doing. I am pressing 'C' and then dragging the circle down.

Do you have an idea what i could have done wrong or which step i could have missed?
Or should i rather start over again.
Thanks for all your help.

EDIT: i thought that up to this point everything should have been correct:

@wires
Thank you Gerry :)

@toystorylab
Knock-Knock.. Who is there? Mr. Blender... :hehe:

@3dtester - Thanks!
You are selecting only visible vertices, because you did not disable "Limit to visible only" (name of this setting is quite confusing - it is basically an Xray in Edit mode).

You have to disable "Limit to visible only" as shown on the right. This way you'd be able to select back faces/edges/vertices from the front.

@rosuckmedia - Thanks!

Looks good. The only problem I see, is that the cable snaps out of Capsule lock.
This because Driver Sphere at this point should have already been rotated more counter-clockwise
Cable does not have enough flexibility to react that fast to sharp turns. In part because it is being dragged on a rigid floor.
In general, animation should be crafted very carefully. Without forcing cable to make extreme, sharp turns/twists. And done maybe slower than normal.
It can be speed up afterward, when animation is baked into Soft Cloth track.

So it should be more like:

https://forum.reallusion.com/uploads/images/6ab854d5-3fac-4b95-b98a-0323.jpg



Also, do NOT hide rigid body objects (Capsules, Spheres). Physics for not visible rigid objects do not work well.
If you need to hide them, convert them to Dummies instead.

Update
So here... If driver is animated properly, you may even *lift* some physics restrictions and even play animation in realtime.
I have attached this project as a demo: https://www.dropbox.com/s/xubvc67ckbcm0m4/Flex_test.zip?dl=0

@4u2ges, thanks for the enlightenment!
Happily done with the Blender part. I like the 2.80 UI a bit more though ;)
iClone plays well with my attempt. The 'tube' proofs itself quite robust :cool:

I got attached to 2.79. Can't break the relationship in favor of 2.8.
There are couple of things I do not like about this version.
One in particular, your favorite now "Limit selection to visible".
Well yeah, in 2.82 they renamed it to Xray and moved it to the top (it says - undocumented operator :ermm:).
But damn it! It does not have a shortcut and I cannot figure out how to make one. :angry:
I keep switching it constantly while working with the mesh and I made a shortcut for it in 2.79.

Let me know If anyone knows how to make a keyboard shortcut for this Xray button in Blender 2.82
