I would disagree, it is in fact highly relevant. If I take an idealised onion
dome and divide it in half, I do not get this part.

According to my book on Russia and the Winter Palace, there is no such
thing as a standard onion dome,

I said idealised, not standard.

I am sure they did. But they didn't make things that had figure eight cross
sections much of the way up, if I am not much mistaken.

Compare to the panel quarter cylinder. That actually IS 1/4 of
something.
Agreed.  It is a quarter of what you get if you put 4 of them together,

It is more than that, it is a quarter of a *cylinder*, a geometric figure, not
just some random shape that has no analogue in real life, like this one is.

Your arguement is flawed by assuming that domes are circular, or even
elliptic.  They are not.

I mean in cross section horizontally, Please provide a cite for a dome that is,
in cross section horizontally, a squashed figure 8.

OK, so what would you call it that enables a user to locate the part?

Partial (as I said before)

And I still need to know the Category for it
