Military Specification: Digital Representation for Communication of Product Data: IGES (Initial Graphics Exchange Specification) Application Subsets

摘要

This specification identifies the requirements to be met when product definition data is delivered in the digital format of the Initial Graphics Exchange Specification (IGES) as specified by its American National standard, ANSI Y14.26M. Discrete subsets of the ANSI Y14.26M entitles are identified by class according to the application for which the digital data was prepared. The digital representation of product definition data shall be one or more of the following classes as specified by the contract or other form of agreement: Class I - Technical Illustrations, Class IV - Engineering Drawings, Class III - Electrical/Electronic Applications, and Class IV - Geometry for NC Manufacturing. Additional classes are expected to be added in future versions of this specification as soon as the technical work codifies their requirements and validates fitness for use. (rh)
