[Chimera-users] Fit map in map

Hello, I was just searching the archieves and I understand now that my last question was alittle dumb (i.e. the x,y,z rotation angles are not helpful). In this case does the "Rotation angle" and the " Axis" define a single rotation that transforms the "Fit map" to the "with in" map. Can I draw the axis using a .bild file (i.e .arrow with start and end coords given by axis and axis point). if I want to compare several maps to one reference, is it possible to define a single axis for them all? such that i can compare them all just by the magnitude of the rotation? does this make sense? thanks in advance sean
