I tried it but at first I saw no mean to bend the tube... till I find
that double clicking on the end of the tube allowed to bent it. Then I
tried to add more control points by double-clicking elsewhere in the
tube, but most of the time except when I'm just on (invisible) control
point I get a Leocad crash ("read access to memory address 0x000030").
Something I noticed: if the piece is rotated before moving CPs the
arrows go in wrong directions.
Overall, when these quirks get solved it looks very easy to use.

Your scheme is certainly workable, but generally the endpoints and their
orientation are fixed by mechanical design. If they rotate while you
modify the center part would not be that convenient (but maybe I am
biased because I can't freely add CPs in your demonstrator).
I would rather use the move tool to fix the endpoints (as it is now) and
the rotate tool to define their orientation.
BTW, what is the "saturn" icon that appeared in the toolbar?

How do we define a part to be a bendy thing?
