[Chimera-users] how to display coordinate axes

Hi Michael,
If you mean axes that will move along with your structures and show how their current coordinate system(s) are oriented, there isn't a built-in option, but you can open the attached BILD object file in Chimera to display such axes. It shows the axes (X red, Y yellow, Z blue). The file should be named with the suffix .bild to be recognized automatically.

The BILD text file is very small and simple.  You can edit the colors, 
scale, offset etc. as desired.  The format is described here:

I hope this helps,
Elaine
