Hi,
  If you want to draw a set of axes matching a particular scale
for your molecule, rather than using the built-in scale-independent
axes in VMD, you'll instead want to draw your own using the VMD
graphics/draw commands. By drawing your own, the scale of the axes
will always match the scale of your atomic structure preserving
whatever relationship you're aiming to create, and the orientation
of the axes will track the orientation of the molecule precisely.

To learn how to draw your own geometry like this, please have a
look at the nice tutorial section by Axel Kohlmeyer that
provides some excellent examples:

Cheers,
