[chimera-dev] Want to Convert PDB to VMRL?

[Tom Goddard]

I suspect the OBJ export outputs the model in the local coordinate 
system of the model while the VRML export gives you the global 
coordinate frame which includes any interactive rotations you did.  That 
is a bug.  The OBJ code should use global coordinates so you can orient 
the model as you desire for the output.
