第四代设计（4GD）管理系统的优势

4GD has several advantages over previous generations of data management systems:
1 A, L5 E0 w* P! a+ D. `8 q• Flexible organization of design data
3 _6 J: D: ~# T' T# o+ [8 a. vThe collaborative design content can change dynamically as the design evolves.
Designers are not limited to viewing the product in predefined subassemblies.
• Independent lifecycles
- M  v) W- e! m4 Z" w1 eEach design element has its own lifecycle. You are not limited by the lifecycle
of traditional assemblies. Each design element has its revision and status.

; Z1 h: F5 R7 V• 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

• Efficient working sets

the next highest parent assembly that contains all the design elements.
• 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
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
