Dear Fellow TechNetters:

     Is the current trend to model component land patterns from the center
     of the part or from pin/pad 1?  Whichever is the answer, what is the
     justification for doing it that way?  We are embarking on a project to
     automate conversion of PADS board layout to a 3-D Unigraphics assembly
     model and the aforementioned issue is a critical one.

     Thanks in advance for any help and advice.
