第四代设计（4GD）管理系统的优势

4GD has several advantages over previous generations of data management systems:
" F( c. u- [1 K6 Y• Flexible organization of design data
% v. N$ Y* B) `" ~1 _The collaborative design content can change dynamically as the design evolves.
1 w( u! `5 L+ Z6 GDesigners are not limited to viewing the product in predefined subassemblies.
• Independent lifecycles
' D1 W9 m! u4 X. P( J# |6 x! O- OEach design element has its own lifecycle. You are not limited by the lifecycle
of traditional assemblies. Each design element has its revision and status.
+ @, V5 c/ {5 @+ |# ~1 F8 p5 W: ]3 OLikewise, the CAD design owns its position and geometry.
• Multiple hierarchical views
In a traditional product structure, each component is placed in an assembly. To
view a component, you must load its parent assembly. Using 4GD, a design
element can appear in multiple partitions and subsets of the product. When
( N4 X( B) ^! xa designer views partitions that may contain the same design element, 4GD
displays only the unique design elements.

( p8 Z) p/ v, N- A8 k. `, P3 Z' HBecause there is no concept of a structure, very large data sets can be managed
efficiently . Teamcenter loads collaborative designs much more quickly than
  S% y, y+ ]0 k" r* Xtraditional assemblies.
- e, w( B9 N  u9 k• 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
/ c2 a* B3 a$ r3 B" ~5 I) Mrecipe instead of a rigid subassembly, the context of the workset can be updated
to include new design elements created by other designers. For example, if the
