Thanks, Edward.
Yes, doing more manipulations with space-filling/surfaces is something
I've been thinking about adding. There is less that can automated when
things become more irregular and the meshes become more complex,
however. These tools can be used to do some mixing of surface and
ball-and-stick representations for printing. Here is one I did to
illustrate the base stacking within a B-form DNA duplex surface
(somewhat difficult to photograph):
