Product Definition Data Interface. Volume 1. Executive Overview.
Abstract
The objective of the Product Definition Data Interface (PDDI) Project, sponsored by the Integrated Computer-Aided Manufacturing (ICAM) Program Office of the United States Air Force, is to develop and demonstrate an exchange specification which would allow the replacement of engineering drawings with an electronic interface between engineering and manufacturing functions. The PDDI Project is organized into two tasks: Task I - Evaluation and Verification of the Initial Graphics Exchange Specification (IGES). Task II - Development and Demonstration of a Product Definition Data Interface. The Initial Graphics Exchange Specification (IGES) is a format for the digital representation of data needed to define a part or an assembly. It was developed in response to the needs of industry for a solution to the problem of interfacing dissimilar CAD systems. This report is concerned with Task I of the PDDI project and describes the establishment of a test methodology for evaluating the effectiveness of IGES implementations. The work is concerned with three fundamental objectives regarding IGES: Establishment of a test methodology and procedures to evaluate IGES translators. Determination of the extent to which IGES defines product definition data. Evaluation of the level to which the CAD vendor/user community has been able to implement IGES, and the identification of problems in current implementations.
