. All goes fine with the creation within the tool graphically, but when I import it into my PADS library (ver 9.3.1 if relevant) the 4 th pin does not have the large thermal pad associated to the hole (see image

. IPC uses the Pad Size to calculate Thermal Relief and Proportional uses the Anti-pad to calculate the Thermal Relief. The big difference is that the Anti-pad is a much more stable number because it's calculated by the hole size which is always consistent
