We purge unused padstacks when we create new physicals; especially when we
create a make-from.
It keeps the library database a little smaller, after all who needs a 3 pin sot
that has 15 padstacks attached to it?
I believe that it also helps because Allegro has a habit of remembering old
junk that takes extra time to clean up.
Please let me know if you have any questions.

Chris,
Thanks for the reply. I don't use Library Workbench, but I think I'll start
doing the "purge" on every design anyhow.

Gary,
Just FYI, if you ever want to use the Library Workbench (in Allegro Design
Workbench) then the library import facility requires that all the parts are
squeaky clean, including purging unused padstacks.

Hey guys,
Are you purging unused padstacks before sending your design to Fab (Tools ->
Padstack -> Modify Design Padstack, Purge -> All)?
If so, what is the benefit? What is the downside to not purging? Is it simply a
database cleaning function?
Thanks for any responses.
