I'd try to create segments of flexible axle parts duplicated (to make both rails), a special segment with beam+2 axle segments, then create a special LDCad template using those segments. But imho it's worth the trouble only if you have many similar bent parts to do!

The thing is I have a model that has quite a few more of these constructions in all sorts of forms and curves and even more complex, twisted too, like a DNA streng, if you know what I mean.

In the model if have in mind there are even more liftarms on the axle and those are actually closer to eachother so you get a very nice curve, if you can get the idea.
On the ends of the axle there are half pins so you can connect to other technic beams and elements with pin holes.

I would try making two custom donors: one with the liftarms plus some straight 20 LDU flex segments inside the outer two holes; and a second with side-by-side flex segments for the space in between. Use static placement for the first and deform placement for the second…??

Another option is separate path parts with identical path points. Once you have the flex axles formed, duplicate the path points in a new file and replace the flex segments with static liftarms. This has the advantage of letting both components take color 16.

I want to achieve something like these, purely illustrative, no where near the real model.

(2022-05-17, 16:06)Jaco van der Molen Wrote: OK, I added snap info to axlehol8 and now the beams actually snap to the ends of the flex axle, but not the mid section.
Since axlehol8 is used in the parts that make up the ends, I thought this should work.
Since axlehol8 is used in ldcFlexAxleMid.dat too?

(2022-05-17, 17:08)Philippe Hurbain Wrote: I can say it's OK now.
Attached the new files (donor with connectivity and new template) and the test LDCad file.
Drawback, file is huge...

(2022-05-17, 17:36)Jaco van der Molen Wrote: Ah! You sir are one of kind.
I cannot get it to work. I've put the template in the templates folder and the dat in the donor folder.
My parts do not snap either.

I am missing something. Can you please share ldcFlexAxleDualEnd Cap, D, E, F and G too?

Tricky isn't it?  
Actually, I used axle connexion to allow auto-orientation of part. A pin connection might work in non-twisted configuration, but otherwise it's better to use a part with axlehole and replace it later with a beam.

(2022-05-17, 18:50)Jaco van der Molen Wrote: [EDIT] Works good with axle holes, but then replacing with beams is difficult, since the center is elswhere.
