3D Model Based Definition
NAS 9300-007 :
Model Based Definition (MBD) is a set of concepts, processes, and tools that allow the creation of an annotated 3D product definition based on a 3D solid model. The MBD dataset includes all Engineering Intent requirements (including Process Specifications, Geometric Dimensioning & Tolerancing (GD&T), and other required information). Combined with product lifecycle management (PLM) attributes, a parts list, and general notes, this constitutes an authoritative, single source of master product definition data that does not include or depend upon traditional 2D drawings. The MBD dataset defines complete requirements for a product in its nominal condition as well as permissible limits of variation and other acceptance criteria, providing all the data needed to plan, fabricate, and validate an article of product hardware.
