= Maximum Lead Width (or Component Lead Diameter) In Through Hole > Axial though users have to enter both Min and Max values for b and the calculated footprint name uses the nominal value for b, for W, and not Maximum Lead Width as I expected

. IPC considers that both round and rectangle leads are the same, but PCB Libraries, Inc. believes that the round terminal lead consumes more volume in the hole than a rectangle lead and therefore the hole over round lead should be larger than hole over rectangle lead
