Tildes in Primitives - Orion Pobursky - 2022-01-18

I'm not certain that tildes are right for use in primitive descriptions. Lots of primitives are built from other primitives. None of them have tildes.
Thoughts?

It makes some sense to tilde primitives that can't normally be used directly in part or subpart. But I'm pretty sure that the need to do so will happen (or already happened!) So it must remain just a hint.

The tilde should be used for primitive “subparts” with no single use outside its parent parts. At least I think so.
RE: Tildes in Primitives - Gerald Lasser - 2022-01-18
That's my part.
I used the tilde because I considerd the "Finger" to be the main primitive to be used in a part.
The single side is not of so much use directly in a part and as it is common for the related "fingers" I used a tilde in front.

I would like to rephrase that:
"The tilde should be used for primitive “subparts” with no single use outside its parent primitive."
How about a redesign of all the click lock and finger primitives?
I think we have removed the soft edge/corners on one of them, and I remember one containing a reduced resolution on the locking mechanism.

As I did the clh6x, I can have a look a the rest of them as well.

I think, maybe, some things can be further generalized and reused. I'm still not convinced the tilde is needed or necessary in either case

Could we please continue the discussion about the 'primitve subparts' and the tilde? Simply take them as prims or add a tilde in front to make them invisible?

Invisible to whom?
The average model builder, or user, never need them, but all part authors should find and use them.

I'm opposed. They don't need to be "hidden" for anyone. Regular users don't see them and part authors may find them useful.

I do have several such primitives (in https://www.ldraw.org/cgi-bin/ptscan.cgi?q=%7Etechnic+pin+primitive&scope=header), if we all agree I can edit them.

Invisible is not the right wording. Maybe can define it as: The tilde in front of a primitive description shows the part authors, that this is a subprimitve.

The consensus is no tildes in primitives. Therefore, they will be removed

I can see the logic of the tilde for sub-primitives, but I think it would need to be reflected in having a p\s\ subdirectory so that the usage is clear to part authors.
For cases where the sub-primitive is used directly as a primitive, it should be copied in the main p\ directory, I guess?
If that feels redundant or superfluous, then I'd consider it an argument against using the tilde.
