How do I add a drill to PCB

Hi !

Firstable i'm sorry, i'm a french student so that's why my english is not perfect...

I'm working on a PCB design and I'm trying to add drills to my Vias and Pins. I configured them in the Padstack Designer where I could see the drill hole. But when I update it to my design, there's no hole on my board and even less on my artworks... =\

I read a lot of threads here and on other forums but I did not find an answer. =(

Thanks.

I am using allegro 16.5.
