Dear Vince,
For Chimera (or any other molecular modeling program) to open a PDB file, it should be kept as a PDB file, which is plain text.
<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/tutorials/framepdbintro.html>

The font used to display the text is a completely separate issue.  It is not a Chimera question.  To display any text with constant spacing, you just have to use a fixed-width font such as Courier.

I hope this helps,
Elaine

Regular .text (to pdf and illustrator ) file fonts are horrible, Is there is way to keep same space between columns and change the fonts size and style that respects pdb format. Therefore I want know is there any additional option in chimera to export coordinates? in a nice way so that if someone copy these coordinates from the article they should be open in chimera with out further editing.
