Model Based Definition

Many large automotive and aerospace companies are switching
to a design process called model based definition (MBD) where the 3D data model
now includes all the 2D content once shown on drawings. Basically, instead of
having a CATPart file and a CATDrawing file (in CATIA) there is now only a
CATPart file which contains all the information and attributes from the 2D
file.
