I guess today is your lucky day because I have had to do something very similar.
First of all, be aware that the LSynth primitives used for pneumatic tubing,
flex tubing, flex cable, fiber optics, and rubber bands are all basically the
same thing. They are just cylinders with different sizes. In fact, flex cable
and fiber optic cable actually use the very same dat file which is LS31.dat.
The only difference is that the fiber optic cable has a flared end on it.
So this means that one option is to simply go edit LS31. You’ll see one
cylinder here and you can change the radius just by changing the non-zero
numbers. Of course if you do this then LS31 won’t be right for the other types
of parts any more. Another option would be to make a new file called, for
example, jetro.dat. After you have run LSynth, fire up a text editor and do a
find and replace with LS31.dat-->jetro.dat.
One final option is what I actually used on
this render
(illuminated in red) which has 16 fiber optic cables. For whatever reason, you
will find that the algorithm for fiber optic cables creates a HUGE number of
cylinders. I had over 20,000 and this was choking both MLCad and my renderer.
I solved it by using pneumatic tubing (LS21) instead and just shrinking the
radius. This decreased the number of cylinders by a factor of 10 and still
looks fine. Since you actually want a bigger cross section anyway, you might
simply try using pneumatic tubing instead. Just use a color of 47 (trans
clear).
