Probably the simplest way does not involve MODELLER. Check out SCWRL (http://dunbrack.fccc.edu/SCWRL3.php); it's a simple program designed for the exact task you described. It is available for various operating systems.
 
Good luck,
 
Tom

Hi,
I would like to use modeller to put sidechains on my 'backbone only'
structures, but without moving the backbone atoms at all. Could you tell me if
this is possible and maybe point me to the part of the manual which describes
the process.

Many Thanks
Diana
