I guess if I ever got this <#$@!!> XML parser working, things could be reswizzled to produce a pre-16 tech file. Newer features would have to be filtered, physical/spacing rules would have to be handled, the new rules sets would have to be translated back into the old-style constraint sets, the rule-rule assignment tables would have to be regenerated, etc., etc., etc. Quite a project. Right. Durn near impossible. :) -- George Patrick Tektronix, Inc. Central Engineering, EDS Application Support P.O.
