第四代设计（4GD）管理系统的优势

4GD has several advantages over previous generations of data management systems:
; s. H( M& P9 U$ `• 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.
' l+ m# b" I; m4 f1 ~• 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.
- z$ w2 ^& V8 A9 L7 NLikewise, the CAD design owns its position and geometry.
6 \' X- U7 E: V3 b5 W5 T• Multiple hierarchical views
In a traditional product structure, each component is placed in an assembly. To

( R9 {" t  f5 `  qelement can appear in multiple partitions and subsets of the product. When
( j) \7 {! V9 ^& n9 `4 J6 wa designer views partitions that may contain the same design element, 4GD
displays only the unique design elements.

Because there is no concept of a structure, very large data sets can be managed

traditional assemblies.

Designers check out only the design elements they need. To reposition a design
element, there is no parent assembly to check out and lock.

Designers can work with adjacent design elements, without having to check out
the next highest parent assembly that contains all the design elements.

8 `% b6 z; u: I9 q. t4 vBecause designers access the design elements in their workset using a dynamic
  _, i9 j% \: X; r/ O. orecipe 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
recipe searches for all design elements within a spatial volume, reapplying the
recipe opens any new design elements within that volume.
