The best way, IMO, is either in imperial OR metric, not both. Protel has certain peculiarities which impinge negatively upon dimensional accuracy when switching units from one standard to the other. That is, you're asking for trouble on the mixed-mode (mil/mm) question. As for SMD/thru-hole, it's easy, design-wise, but mfg is a little more complicated than one or the other, and your options become a bit more limited in terms of automated fab. aj * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * To post a message: mailto:[EMAIL PROTECTED] * * To leave this list visit: * http://www.techservinc.com/protelusers/leave.html * * Contact the list manager: * mailto:[EMAIL PROTECTED] * * Forum Guidelines Rules: * http://www.techservinc.com/protelusers/forumrules.html * * Browse or Search previous postings: * http://www.mail-archive.com/[EMAIL PROTECTED] * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
