What is Model Based Definition
(MBD)?
 A process of re-using the 3D CAD model for downstream
customers.
 The Annotated Master Model contains all of the information
needed to define the product in an annotated and organized
manner in order to be automatically extracted by non-CAD
users, thus replacing a traditional drawing..
 If properly implemented, nonrecurring costs can be cut
between 50% and 70%, and the time to market reduced by
as much as 50%

MBD Realization
 This is done utilizing various tools commonly available and in
a CAD agnostic format, allowing even the smallest supplier
to utilize this delivery method without additional software..

MBD Schema?
 Previously, 3D CAD models had an accompanying 2D drawing.
 All product definition previously shown on a drawing is now
defined and displayed directly in the 3D CAD model
 This is accomplished by utilizing a combination of annotations and
naming conventions to organize the 3D solid model.
 The 3D model becomes a single master source for obtaining
product definition data and eliminates the need for a 2D drawing.

MBD and QIF
 ISO 10303 STEP AP242, Managed model based 3d engineering
 Is AP 242 the “CAD agnostic” Annotated Master Model that is
the bridge to QIF?
 What is the current state of development and test as a Standard?
 Who has committed to produce?
 Without AP242 producers, consumers will be reluctant to
commit.
