Gary,
The only negative that I'm aware of has to do with the ssm symbols in the
padstacks.
I recently had a job were Allegro was having a problem refreshing the ssms
(neither Refresh Padstack or Update symbols--> Shape and Flash Symbols would
work)
I ended up deleting the offending symbol, purging padstacks, and replacing the
symbol, which then worked fine.

Hey Dave,
Thanks for the response. I worked a contract job this past March, and the job
shop had as a checking item that padstacks were purged.
I've been using Allegro since 1995, and before March, I had never ever purged
padstacks (with no known negative effects!).
I was just wondering what might happen at some point if padstacks were not
purged.

Gary,
I purge as part of cleaning up the database.
I have a little batch file that I run at the end of the job.
One of the lines in the batch is:
dbdoctor -drc -purge_vialist -purge_padstacks %1
I figure, it's free and easy, so why not.

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.
