I agree but I'd like to have a short discussion in case anyone has strong feelings against.
I should think it would have to be closed, in case the assembly is rendered in a transparent color.
(The other possibility is that it forms a closed solid when assembled—i.e., there are no interior unmatched faces—but then why would it need to be an assembly to begin with?)
