Depends which set of drawing you want to send to the consultant: a specific already published set, or one that reflects the current state of the drawings.
I find it easier to publish to a spool folder on my desktop and then move the folder of the published set with the date added to the name into the appropriate folder : 'HVAC to'> HVAC background 090929.
Just one method.
Conversely some like to publish right to the folder the set will reside in for eternity. Too often end up sending a published set to the wrong folder.
