Hello! My question is: it possible not just to measure but to change the angle between three atoms (e.g. A1 and A2 fixed, A3 rotated in the plane spanned by A1-A2-A3 with radius A2-A3)? What I really like in Chimera (and miss in other molecular modelling software) is the possibility to move/rotate only the atoms selected, which is great e.g. for pre-aligning two molecular fragments when modelling transition states. I know chimera is actually rather intended to be used for large molecules but it could be a great tool for modifying/building structures if only it was easier to modify structural parameters like bond lengths, angles and torsions (which I saw is possible). Kind regards, Thomas Mitterfellner
