Hi Pilou, I forgot to answer these parts:

> In general on the array functions does exist a limit (security) of numbers of "Copies"?

No, there is no special limit. I thought about this for a bit, but it is hard to decide on a limit that works everywhere, if you have a complex object then the limit would need to be smaller, if you have a simple object it is possible to make a lot more copies of it. So I just decided not to set any limit on it.


> Pss When you take a "face" of a "Box3D" and make an "Array circular" function ---> crash !

Good testing, Pilou! Thanks for finding this, I will work on fixing this for the next release.

This is a good idea, I think it is possible that someone could put in "0" for the number of copies in Z thinking to disable z copies. I'll fix this one up too.
