How to Convert Mylar Aerospace Drawings

Aerospace design drawings were traditionally created and stored on mylar sheets. But, with today’s newer 3D CAD technologies, Mylar film has mostly been replaced by 3D CAD models and dynamic virtual viewing.  This can lead to a dilemma for organizations that have large stores of old aerospace design drawings on Mylar. 

As these drawings have aged, most will have deteriorated.  In order to preserve the design information in 3D CAD, the drawings will need to be scanned and converted.  However, the Mylar deterioration makes the scan and conversion process much more difficult.

Converting Aerospace Mylars to Catia

An “Aerospace Mylar” is an un-dimensional engineering drawing on a stable base polyester material called Mylar.  Aerospace mylar drawings have a highly accurate tolerance of +/-.005” and are typically very large format (up to 48” X 180”).  During the manufacturing process, the part that is imaged on the Mylar is cut in metal, then place on the Mylar to check for accuracy.   Because of the requirements for very tight, accurate tolerances in the building of aircraft, accuracy is highly important.  The slightest deviation can cause mal-functioning parts in the finished aircraft.
