hi Miguel, I like solid hydrogen bonds for several reasons: 1. backwards compatibility with Chime, even if the syntax for rendering them has to be different. 2. in some cases, I find the dashed lines have a somewhat awkward appearance. they don't directly contact the donor and acceptor (or the backbone participants in 'set hbonds backbone'), and the spaces between dashes are sometimes disconcertingly large. 3. hydrogen bonds are weaker than covalent bonds, but they are still relatively strong for weak bonds, and they are directional and specific. in a lot of cases, I think it is important to convey a sense of solidity in a structure honeycombed with hydrogen bonds. one example is a DNA double helix; another is a protein alpha helix. dashed lines don't have the same impact IMO. would solid hbonds be difficult to accomplish from a programming standpoint? regards, tim -- Timothy Driscoll molvisions - see, grasp, learn. <http://www.molvisions.com/> usa:north carolina:raleigh "I still say a church steeple with a lightning rod on top shows a lack of confidence." - Doug MacLeod ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
