It is a better question to ask the IPC Designers Forum. They answer a billion questions just like that every day. I have copied Jack Olson, a well-known design guru who knows all and sees all in PWB design. He can direct this question to the Designer's Forum, and he can probably also answer your question for you. There are a number of Allegro experts in that forum.

Fellow TechNetters:

   I did not receive any input so I decided to post again.   Sure hope the PWB gurus are online.

Fellow TechNetters:

   Which ICON in the above stated program can I find the DRLL HOLE SIZE for any drill hole within a PWB form Factor?   I found the drill size list.
