[Chimera-users] Group cylinder with a PDB and fit together

Hi all, I created a some cylinders in chimera to visualise the symmetry axis and the rotation center of a hexametric structure. Is there a way to fix the position of these cylinders relative to the pdb structure? So when I fit the structure, the cylinders will also rotate in the same way. And, by the way, is it possible to duplicate these cylinders, or do I have to create a .bild file and import it several times? Thanks for your feedback. Mario
