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. Anthony Bundrant Design Engineer Bell Helicopter Textron P.O.
