第四代设计（4GD）管理系统的优势

4GD has several advantages over previous generations of data management systems:
* \2 ^2 Q2 y" w: h* |, N) k• Flexible organization of design data
The collaborative design content can change dynamically as the design evolves.
Designers are not limited to viewing the product in predefined subassemblies.
& c0 v; Y  b5 F8 x6 W• Independent lifecycles
Each design element has its own lifecycle. You are not limited by the lifecycle
of traditional assemblies. Each design element has its revision and status.
Likewise, the CAD design owns its position and geometry.
( p+ R6 |1 o( D3 H& c• Multiple hierarchical views
In a traditional product structure, each component is placed in an assembly. To
* I" ?# j0 T8 U1 ^, X: ^9 kview a component, you must load its parent assembly. Using 4GD, a design
# q- v+ l0 S. r/ x' b# xelement can appear in multiple partitions and subsets of the product. When

% G% ?9 t$ n; O6 \) M& w$ B• Very large data sets
Because there is no concept of a structure, very large data sets can be managed
efficiently . Teamcenter loads collaborative designs much more quickly than
traditional assemblies.
& J, w# s" n# U' ~• Minimal data locking
Designers check out only the design elements they need. To reposition a design
element, there is no parent assembly to check out and lock.
• Efficient working sets

• Concurrent work capabilities
Because designers access the design elements in their workset using a dynamic
recipe instead of a rigid subassembly, the context of the workset can be updated
