Dear all, is it possible to generate symmetry-related copies of a surface model created by the shape command? I am interested in masking out certain map regions related by symmetry. I got the right shape at the right place but now cannot figure out how to create the shape symmetry mates. The sym command followed by the model number of my shape complaints that no molecules are specified.
