==Use of the 3D digital data set==

[[File:QIF 3.0 contains PMI data.png|alt=QIF 3.0 (Quality Information System) is a neutral CAD file format built on ANSI and ISO open standards and containing PMI (Product Manufacturing Information) semantics and other metadata, designed for future compatibility and traceability throughout the product life cycle, especially in automated processes and engineering applications.|thumb|430x430px|QIF 3.0 Quality Information System is a neutral CAD file format]]

Modern 3D CAD applications allow for the insertion of engineering information such as dimensions, GD&T, notes and other product details within the 3D digital data set for components and assemblies. MBD uses such capabilities to establish the 3D digital data set as the source of these specifications and design authority for the product. The 3D digital data set may contain enough information to manufacture and inspect product without the need for [[engineering drawings]]. Engineering drawings have traditionally contained such information.<ref>Thilmany, Jean, [https://www.asme.org/engineering-topics/articles/design/digital-tolerance "Digital Tolerance"], "MBD is a method of annotating computer-aided design models with geometric and tolerancing information that allows engineers to draw directly onto a 3-D model.", ASME.org, March 2011.
