I am currently trying to build a TO-220 leaded transistor in PCB Libraries. 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). I also noticed that graphically the large pad shows as expected (see image). And as for the version I am on 2012.47 In any case I will add them directly to this post anyway.   |

I was also building a TO-220FP footprint, horizontal. I put the numbers in, saved it to my library, clicked on it again and it turns vertical with all the wrong dimensions, h was 16.4 now says it is 3.6. I output it to OrCAD PCB Editor and it comes out ok. Also I don't understand what the b dimension is. Is it the thickness of the terminal? I am using 0.51 version. A little confused.
