How to Recapture Obsolete CAD Data
While we've written before about conversion of old mylar and paper drawings to CAD, as well as the conversion of obsolete CAD data to newer formats, the importance of what we do cannot be underestimated, and deserves another review.
Some industries -- notably Aerospace and DOD -- need to retain their CAD drawings for at least the life of the equipment, sometimes longer. Often, this means retaining the data for 30-100 years. Similarly, other long-lived equipment, such as that used in Manufacturing requires current versions of drawings when parts need to be replaced or re-engineered. One other industry that has requirements for preserving old drawings is AEC, particularly when it comes to preservation and repair of historical buildings.
