There’s at least a dozen chemical structure editors running under different kinds of licenses and platform, and (ugh) none of them are truly satisfactory. The latest one I’ve checked out is ChemDoodle, which is somewhat new and have some good things going on. The existing reviews on the Net dates to 2004/5, so a fresh look at the current capabilities will be useful to the chemist community. A more comprehensive look will come later (as in, a month or two later); this post is interim notes to remind myself for later, and an invitation for readers’ comments. What other sketching software should I know about and what are your experiences with them?
