UCSF Chimera, Just discovered your software and it's amazing! Thank you for making it free for academic use! I just have a quick question regarding the possibility of "filling-in" or changing the linewidth of ribbon structures. I would like to have my ribbon structures completely filled in and not hollow, so when I view them with "Side View" opition, I don't see emptiness inside. I've attached two photos. The first is a view of the ribbon structure from the outside. The second is a view of the ribbon structure view from the inside, where you can see that it's hollow. I would like to know what function or command to use to correct this so it's complete solid inside. Sincerely, Alex YornPhD Candidate Department of Molecular BiologyUniversity of Toronoto
