9. 23/7/4:SB-PDT:Not protectively marked copyright BAE SYSTEMS 2005 Immortal Information Implications When we update a model in 20 years time: CAD System replaced twice The hardware replaced 6 times Given old software on an old computer, we need person who remembers how to use it. Chances of reading old CAD data?
