2 B/ T1 T7 d4 v& C; E* PNX 8.5 introduced the fourth generation of design (4GD) and NX 9 enhances the existing 4GD functionality.
4GD represents a major change in how NX product assemblies are stored and managed in Teamcenter, and how they
are checked out and used in NX.


4 M; R; w  s0 h4 b9 e& v/ KIn 4GD, design elements replace traditional assembly components. Unlike assembly components, each design
element is an independently managed occurrence with its own position, access privileges, attributes, revision
  u- m- b* b4 r: T, Whistory, unit effectivity, and locking status.


This means that when you check out any design element, it is displayed in its correct product location, without the
need to check out a parent assembly.
