Product Data Strategies for the Department of Defense

DoD has undertaken a large-scale project to convert engineering drawings to electronic raster images. While DoDs approach is acceptable for preserving past data, it is not sufficient for new or reengineered product data, and it is not compatible with modern, computer-aided engineering and manufacturing technologies. DoD recognizes this and has formulated a long-term goal of representing its product data in a neutral format known informally as STEP. The international standard defining STEP, however, is incomplete and not yet supported by commercial mechanical engineering software. In this paper, we present a survey of current capabilities in computer-aided design and manufacturing software. We evaluate the ability of STEP to capture data created by that software. We present four alternatives, including STEP, by which DoD and its contractors could utilize more advanced product data than they do today. Finally, we develop a near-term transition strategy for capturing product data in currently-available formats while awaiting the STEP standard to mature.
