[chimera-dev] structure analysis feature in UCSF Chimera

Hello, would it be possible to add the two following features to the "Tools/Structure Analysis" menu of UCSF Chimera: the distance between atom A and a plane of other 3 atoms B,C,D ("the height of a trigonal pyramid with atoms B, C, D at the base ") and the angle between an axis (defined by atoms A and B) and the plane B-C-D ? Thank you very much in advance. -- Best regards, Serge Gorelsky (a Chimera user since 2005)
