You can use the standard chemical drawing packages like ChemWindow or 
ChemDraw to set up a template for this. 

ISIS/Draw is a freely available package for Windows, Macintosh and 
SGI workstations which should also do the job.

A related request: 

Does anyone know of a program (preferably win95) that will produce 
such 2-D H-bonded representations of beta-sheets (and alpha helices), 
with side chains labelled, from the information in PDB files?

Many thanks,
