This is an old problem. It generates extra walls at the boundary of the modifier.
It was already in the Prusaslicer. I reported it but it is not solved until today.

one of many reports, for example: prusa3d/PrusaSlicer#7847

[HappyOldtimer]

Right. Well, that might make it more interesting then, since it doesn't happen in PrusaSlicer 2.6.x. (am not @ the office, do not know the last digit off the top of my head) So this has been solved in PrusaSlicer, apparently : -) Paul

"So this has been solved in PrusaSlicer, apparently : -)"
Are you sure? The newest Prusaslicer available today:

That's why I asked, prusa3d/PrusaSlicer#9787 and several of us have asked prusa3d/PrusaSlicer#9787 , for a painting tool, so that the fuzzy skin can be created where you paint it.
It only makes sense on the outer surface anyway. Currently a modifier body penetrates the model and creates the fuzzy skin where it is not needed.

prusa3d/PrusaSlicer#11594
Whoever solves this first will get the glory...

Sorry for late reaction, have been away couple of days.
But actually: this is in Prusaslicer, with cylinder and no edge lines... so from my perspective it seems solved in Prusaslicer...??

Cheers,
Paul

No Paul, it's not solved, you're just doing something else.
Look at my photo, the latest Prusaslicer hasn't fixed this bug either.
If you insert a modifier body into your model and turn on the "Fuzzy skin" of the modifier, it creates walls inside.

[HappyOldtimer]

Interesting, because that is not what my post was about although i did not mention it explicitly that the fuzzy skin property was added but turned off.

So to be clear: I have added a cylinder modifier, added the property 'fuzzy skin' to it with the checkbox unchecked, just like i did in my initial post.

My post is about the fact that with a modifier with the fuzzy skin property added but turned off, it still produces those wall lines in Orca, but not in the PrusaSlicer version i am using.

Your image shows that you have fuzzy skin turned on, that is not the issue i was/am reporting about.

[DVSVIDEO]

Okay. I followed the list mentioned in the first post:

Load model
Apply fuzzy skin
Load modifier
Set fuzzy skin off for modifier
See lines in sliced model

Here are the results:

As I mentioned before: this is an old problem and I have not read anywhere, in any version update, that this has been solved.
So this is an old problem and since both BambuStudio and Orcaslicer are derived from PrusaSlicer, this problem is inherited.

[HappyOldtimer]

To doublecheck, I did the same as what you did:
Load model
Apply fuzzy skin
Load modifier
Set fuzzy skin off for modifier
See lines in the sliced model.

And I got the same results you dit.
However:
When I look at the model I started this thread with, the behaviour is different. I have loaded a model, applied fuzzy skin, added two modifiers with fuzzy skin off, and there I have no lines in the sliced model...
And that is what I do not understand.
