I am currently restoring "ALL" of the CADD files for my employer, Packaging Systems Incorporated, a custom machine design/build firm. The data base was destroyed when a catastrophic failure ended in the complete loss of 23 years worth of design and drafting work. I have been charged with setting the new standards and back up procedures while recreating the entire data files from left over "Shop Drawings" and others memories.
