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.
