Hi Elisabeth,
	This will place a benzene ring at the center of the view in a new  
residue named "BZN" in a new model named "scatch":

from BuildStructure import placeFragment
from BuildStructure.Fragment import RING6, fragDict

placeFragment(fragDict[RING6]["benzene"], "BZN")

	Let me know if you have more questions.  Though the placeFragment  
function does have some documentation, the Fragment.py file doesn't.   
Sorry about that.

P.S.  I cc'ed the chimera-dev mailing list on this since that list  
deals more with programming questions.
