The drill symbol shape is fixed as a cross.
The size is fixed at 1 mm.

I would like to know if there are any guidelines or any set of rules for defining the drill symbols in Allegro pad stack editor. 

I have noticed that whenever we generate any through hole footprint from the Footprint expert into Allegro, it generates footprint and pad stack files. 

And the pad stack files are having the drill figure, drill figure width & height and drill character defined. 

But I couldn't understand how it gets defined.
