aionys was rig= ht, it's not our old {carna}. It's something new.
Robin asked "Ye= s, but what about objects that don't have clear <face>. e.g. imagine = a rotating rod".

In this case we must define a plane in the middle of th= e axis perpendicular to the axis.
Then we have line-of-sight abov= e the plane spreading to the plane.
In the image attached we can = see that according to what the eye (marked with "line of sight") sees
the rod is rotating to the right.

So in such = gismu we need a place for direction of rotation filled with "zunle/pritu". = If this placed is not filled then the gismu would mean "rotating in general= ".

Incorrect. Under no circumstances do we need a place = for direction of rotation if we define one of the two only possible dire= ctions as the keyword.

For example, if we make the definition be= "x1 is rotating counter-clockwise viewed from orientation x2 about rotatio= nal axis/axes (set if multiple) x3", than the gismu (I'm going to use "gutn= i") can mean all of the following:

gutni: counter-clockwise
to'e gutni / tolgutni : clockwise
no'e g= utni : not rotating (neither clockwise nor counter-clockwise rotation is oc= curring)
na'e gutni : not counter-clockwise (either clockwise or no rota= tion is occurring.)
na'e tolgutni : not clockwise (either counter-clockwise or no rotation is o= ccurring.)

All that is needed for the word is a default direction, w= hich can be changed to the other with to'e and for reasons of historical in= ertia should be counter-clockwise, a place to identify the 'face' when it i= sn't obvious (x2 in the above), and the axis/axes about which the rotation = happens if it isn't the typical axis.
No. = Your suggestion is not universal. Lojban usually allows ambiguous expressio= n 
It's not possible to say "rotating" without specifying in= what direction it rotates.
You need one more case:
"rotates either clockwise or counterclockwise"

Th= is is what was discussed in the chat.

So let's get back to business.
The scrutiny shows that {c= arna} has everything that we need.

Here is my = solution.
1. Take a clock from the wall.
2. Put it on the floor.
=
3. Sit on top of the clock. Just in the middle of the clock! Be carefu= l not to break something in the mechanism.
4. Look at the hands (= pointers) of the clock.
5. See? They are moving to the right of your point in space! Ever= y atom of the hand of the clock is moving to the right.
6. Now st= and up and put the clock to the wall.
7. Wow! The hand is no long= er moving to the right. It's moving clockwise!

So {carna fi lo pritu} means "rotate clockwise".
<= div>
Now what is {se carna}?

Here we= have a minor problem.
When you were sitting on the clock you wer= e the upper part of the axis, namely the part sticking out of the front of = the clock.
By the word "front" I mean that part that has digits painted on it and= hands moving.
What is "front"? What is "face"?
These a= re two-dimensional but one-side objects (like M=F6bius band or something).<= /div>
You can't look at my face from the other side. You will simply = see the back of my head.

This is what we need.
{carna lo crane lo pritu}.

May be the defin= ition of {carna} is really not an ideal one but I no longer support any new= gismu for "clockwise".
It's better to clarify {carna} definition, may be  change it to&n= bsp;
x1 turns or rotates around from the viewpoint (reference frame) = of x2 in direction x3

This has also to = do with the concept of the "line of sight".
Humans have it and this is what "reference frame" usually refers to.
We look forward and see the hands of the clock moving.
E= ven if we are blind we have such body orientation (including mouth, nose, l= imbs etc) so that we are still oriented forward.
What if we had eyes on our backs: {pritu} has also "frame = of reference" place. Therefore, two ref-frames annihilate (sumti/sumti=3D1)= and we are culturally neutral again.

You might ar= gue: what if spiders that have eyes on their limbs learnt Lojban? Would tha= t be culturaly neutral?
We must think about them too!
The answer is pretty clear.
If you have an eye on your leg please use reference frame and speci= fy which of your multiple eyes is looking at the clock.

Still we have "line of sight" left. I think that every human or pro= bably every animal has such feature. I can't imagine any creature without "= lines-of-sensory-input". All sensory organs work that way. Therefore, I sta= te that it's culturally neutral.

I haven't read all the conversation. So may be somebody= has already understood this.
Thanks for your attention anyway.

The direction is from the clock, along its axis, into the wall, which=
corresponds to a direction of rotation by the convention of holding the rig= ht
hand so that its thumb is along the axis and the other fingers curl in the<= br> direction of rotation.

No, that's not what I mean. You don't specify which= direction the objects are rotating. The "direction" you're talking about i= s the reference point.

Okay, wait, I missed the "...corresponds to a direction of rotati= on...." the first time I read it. Still, your x3's only work if you follow = that convention, which requires you to /know/ it in the first place. I don'= t know how known it is, but I'd certainly not heard of it before you mentio= ned it, which leads me to believe "very well" is not the answer.

It is a neat way to shove the reference point and direction of rotation= together, even though it always means "counterclockwise".
