Jeffrey;
Yes, that does help, thanks!

 >I've used the IPC-7351 land pattern generator for around 5 years and
 >never had a assembly house complain about component placement issues.  I

 >Typically I use the nominal settings for the components and the
 >courtyards(spacing around the part).  Using the courtyards as the
 >placement boundary, I can place them with the boundaries touching (i.e.
 >spacing set to 0).  This leaves about 20-25 mils between the physical
 >bodies of the components which is more than enough space for typical
 >parts for pick and place machines.
 >
 >On denser designs or design that have to fit a very small form factor, I
 >occasionally use the "least" setting which still permits enough space
 >between the parts for most pick and place machines.

 >Hope this helps,
