3D model* that includes associative product and manufacturing information (PMI), that define the product in a manner that can be used effectively without a drawing.
*Definition of model as defined in ASMEY14.41-2012

WHAT DOES MBD CONSIST OF?
1) 3D geometry (serves as the basic dimensions)
2) annotations (displayed notes, dimensions, tolerances, characteristics)
3) attributes (metadata and queried data)
4) presentation (saved views, presentation organization)

HOW IS MBD DIFFERENT FROM DRAWINGS?
Drawings REQUIRE experience

We already see in 3D
HOW IS MBD DIFFERENT FROM DRAWINGS?
Drawings REQUIRE all basic dimensions

The 3D model is the basic dimension
HOW IS MBD DIFFERENT FROM DRAWINGS?
