You need procedures and sign-offs. This is a problem no matter what "system" you use. Look into using a simple check in / check out system like CS( which is freely available from the under GNU open license ). > 3) Fab data will reside separately from drawing data for redundancy.

Yepp. Fab House specific. > 5) Are there software packages that automate all/some of this process? Which process are you speaking about?
