Dear Damien,
When you click "Make models" in Multiscale Models, it leaves the  
original input structure as atoms, but shows any additional copies as  
surfaces.  That is the initial appearance, but you can display each  
chain in whatever style you want by using the dialog (select chain,  
act on selected chains).  You could show them all as surfaces or all  
as atoms, for example.

If you already have all the surfaces you want, you could just use  
"Actions... Atoms/Bonds... hide" or command "~display" to hide the  

In your case, I am guessing it would also work to use the Multiscale  
dialog to select chains "with loaded atoms" and then act on selected  
chains to "hide all styles."

I believe only what is displayed will be exported.

I tried 1yau from the PDB, which is slightly different from what you  
get from pdbsum.  From your picture, it looks like the file from  
pdbsum includes one whole ellipsoid-shaped complex, and Multiscale  
Models created an additional copy of that complex.  The file from the  
PDB includes one half-ellipsoid and Multiscale Models adds the other  
half.  But either way, you can control the display as described above.

I hope this helps,
