This three-day workshop is valuable to anyone involved in the design-through-production process and users of product drawings. Anyone involved in the design-through-production process and users of product drawings should attend this workshop. It is desirable for all participants to have background knowledge or experience in the preparation and/or responsibility of definition on product drawings.

Features & Benefits:

• The interpreter of the drawings has the responsibility to obtain and understand the National Standard
• Drawings utilizing the National Standard should be more consistent and reduce the chances of misinterpretation
• If disputes should arise between the company and outside activities concerning the drawing definition, the National Standard becomes the legally accepted interpretation
• Company standards are often taken only as guidelines and, therefore, individual areas develop their own systems according to their own viewpoint.
• GDT Fulfills a QS-9000 Requirement
