Incorrect sweep docs?

It says that it is swept along the z axis, but from what I can tell it seems that it can be in any vector (length + direction):

I'd be happy to fix the docs, unless I'm missing something and it does indeed have to be in the z-axis

You are right, @A-Walrus, that documentation is outdated! It used to be a sweep along the z-axis (the user only provided the length), but it was changed to an arbitrary a long time ago.
