Ram,

This document explains the clearance and mask numbers ... which are not 
as obvious as you might at first think.

The design rules in PCB do not modify file footprints.  The footprints 
are what they are ... when you write them.  This would pertain to 
text-written file type footprints.  I have no idea about footprints 
created in PCB's gui.
