Hi Andy, There is a “scale” command (for example, “scale 2” for double size) <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/scale.html> ... or you can Z-translate with “move z” (for example, “move z 50” to move all models 50 A toward the viewer) <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/move.html> See the links for additional command options. I hope this helps, Elaine ----- Elaine C.

Dear All, What is the command for zooming into a portion of a density map ? This will be just using the command line for the zoom-in instead of using the middle mouse button.

Thanks
