Let me be clear that the hydrogen on the oxygen is a bug. > Is it not possible to provide an option to compel compliance with the > rules of valence ? Using the "auto-adjust hydrogens" is the most effective way to do this. It's very hard to truly "compel" compliance in a free-form draw tool like Avogadro uses. Spartan, for example, compels compliance because atoms and bonds only fit together in certain ways (e.g., an sp2-carbon can only make one double bond). But a perfectly legitimate description of carbon monoxide has a triple bond between C#O. -Geoff ------------------------------------------------------------------------------ Write once.
