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.

Dave

Subject: [PCB_FORUM] Purge 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.
