how to add mechanical drills or mounting holes to a footprint in allegro 16.6?

EuSV

How to add some mounting holes (or mechanical holes) on a connector footprint that previous exists, and requiries 2 more holes/drills for fixing connector to the board? 

I was trying drawing cercles and looking for "drill" propierty, but I don't find any trick for doing this with Allegro 16.6.

The only thing that I find is "add a pin" but doing this way it doesn't work for me; the update symbol gives me errors as Allegro considers them as real connector pins.

How do you do this type of drills?

    I solved this following the steps below:

    • I went to the "add pin" item from bar menu and then I checked "mechanical" option from "options" right tab. Then I chose the "padstack" that I want to put there. And that's how I had drawn my no electric holes. 

    But even doing this way, it gives me errors when I tried to generate netlist and update the board. But I have faced this other issue as follows:

    • This launched that two pins have missmatched because the symbol hasn't two more electric pins. So I tried one more thing, that was to save this footprint with another name, as it was a new footprint. Then I removed the old footprint file from schematic symbols and I linked the new one (the same draw but other name) to this connector symbol from the symbol library, schematic and lib cache. Hence I started the netlist and update pcb board processes and voila. No error.

    So, it makes me think that there was some issue with data that was saved originally in some file at the moment of library translation.

    Thanks for all of your suggestions. They still been helpful.
