[Chimera-users] Apply rotation with precision

[Damien Larivière]

Hi Tom,

Thank you very very much for this solution! It works perfectly.

I have two other questions:

Is is possible in Chimera to display a reference frame? if yes, can we 
display the default one of the software or the one of a 3D structure?

Also, can we modify the reference frame attached to a 3D structure so 
that it possible to align it with the default reference frame of the 
software?

My best regards

Damien
