[Chimera-users] Deleting invisible structures?

Hello all, Is there any way to selectively delete the 'invisible' (undisplayed) parts of a structure and keep the visible parts without having to use the usual atom-spec approach? For example, if I run per-model clipping on a protein, is there any way to delete the part that has been rendered invisible by the clipping? If this isn't possible, is there a way to export only the visible/displayed components of a scene? Many thanks in advance, Max Taylor-Davies
