第四代设计（4GD）管理系统的优势

4GD has several advantages over previous generations of data management systems:
& \5 x- ^4 r' ~+ B* t7 Q4 d• Flexible organization of design data
The collaborative design content can change dynamically as the design evolves.
# N0 }) K/ U# u- j# C4 ]+ h& J2 cDesigners are not limited to viewing the product in predefined subassemblies.
( U7 D0 D8 {0 Q) b0 R• Independent lifecycles
Each design element has its own lifecycle. You are not limited by the lifecycle
4 m' C) d: j4 ~. A# J; C# m7 Z9 Wof traditional assemblies. Each design element has its revision and status.
Likewise, the CAD design owns its position and geometry.
• Multiple hierarchical views
) B) F6 y( u- a) gIn 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
: w6 s, w% n. n7 Belement can appear in multiple partitions and subsets of the product. When
8 g' K( k% q% w5 p% t. ?: ya designer views partitions that may contain the same design element, 4GD
displays only the unique design elements.
9 i1 g- J/ N0 i2 ?• Very large data sets
) x' Y$ O, c  ]" f$ E' NBecause 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.
• Minimal data locking
Designers check out only the design elements they need. To reposition a design
5 O; S  ?  t0 p* n5 [1 Belement, there is no parent assembly to check out and lock.
; H) ?$ L" X2 O, M0 E• Efficient working sets
- w0 o" g' _: Q- XDesigners can work with adjacent design elements, without having to check out
the next highest parent assembly that contains all the design elements.
& X. a- b0 ^# Y( D! o• Concurrent work capabilities
3 B" s0 B0 Y% p6 fBecause 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
to include new design elements created by other designers. For example, if the
; u# A# `+ O6 U; s8 B7 D" Nrecipe searches for all design elements within a spatial volume, reapplying the
recipe opens any new design elements within that volume.
