Hi Zooen,

In most places where that could occur it gets broken up into separate objects.

But one way to do it currently is with the new move face, if you move a face far enough that it divides the solid into 2 pieces you will get a brep object with a disjoint shell:






Sometime soon I'll be fixing it up to separate those into 2 separate solids.

re:
> But these are not disjoint FACES, it is a "double solid" of sorts.

Yes actually it's called a "disjoint shell". In CAD topology there is usually a topological container called a "shell" that has a list of faces in it. There isn't anything about the topology's structure that ensures that all faces are connected to each other.

Hi Michael,

Thank you for this information.

I have not yet fully integrated these latest developments into my daily practice.

I think "le père Noël" will grant your wishes for Christmas! (Note: corrected on Larry's advice, read the following posts below)

Aw, Zooen, I think he deserves to have his wishes granted THIS Christmas!! ;-}

And to the topic/question you raised, I think Michael's answer is both surprising and quite interesting. I really appreciate these little tidbits explaining the "why" of how things work!

Hi Larry,

Larry@ Aw, Zooen, I think he deserves to have his wishes granted THIS Christmas!!
Of course you're right. I'm on the old continent, and in my mind I was thinking of Father Christmas (translation error). Right, I'll quickly correct that (he's still asleep, le père Noël he's an old man, like me!!).

Larry@ And to the topic/question you raised, I think Michael's answer is both surprising and quite interesting.
I agree with you on that point. And above all, we must always remain curious.
