[Chimera-users] Display axes for global frame of reference?

Hello All, I'm considering using Chimera as my general purpose modeling graphics front-end and have run into a snag. I have a protein that I need to globally translate and rotate to move several residues to be oriented along the x, y, and z axes. In InsightII, there is an option to display the global coordinate system in the main graphics window, so that it's easy to manipulate a structure to a given orientation. Is there a way to display the global axes like that in Chimera, and is it possible to write out the transformed coordinates of a PDB file without a lot of difficulty? Thanks, Andy
