Abstract. CAD software used to design mechanical parts continues to evolve and Product Lifecycle Management (PLM) processes continue to advance, but the transfer of data between mechanical designers and others in the enterprise, such as manufacturing, inspection, and product sustainment, has changed very little in the last 15 years. Current Model-Based Definition (MBD) is design product geometry centric, typically containing Geometric Dimensioning & Tolerancing (GD&T), annotations, Bill of Material (BOM) and limited processing information stored as Product and Manufacturing Information (PMI). Build data today is comprised of a combination of electronic and paper documents spread across many files and multiple formats, (i.e. PDF, HPGL, JPEG, STEP, IGES, ASCII, QIF, MatML, etc.). This assortment of delivery formats is not linked to the CAD geometry, making data transfer and design intent difficult to communicate and interpret. As a result, today’s manufacturers must review, translate/interpret and/or re-enter the design data, causing their manufacturing processes to be labor intensive and prone to error.
