I don't quite understand what you have in mind. Ball-and-Stick diagrams of  
all atoms in a protein? Arrow-and-helix diagrams presenting secondary  
structure?

Nevertheless I'd recommend that you look at DeepView  
(http://www.expasy.org/spdbv/index.html) which can create images of  
protein structures in a variety of formats. For that it uses the  
coordinates determined by X-ray crystallography or NMR, these can be  
obtained from OCA (http://bip.weizmann.ac.il/oca-bin/ocamain).
