第四代设计（4GD）管理系统的优势

4GD has several advantages over previous generations of data management systems:
• Flexible organization of design data
# y# w! m$ t$ t% V1 R2 zThe collaborative design content can change dynamically as the design evolves.
Designers are not limited to viewing the product in predefined subassemblies.
• 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.

• Multiple hierarchical views
In a traditional product structure, each component is placed in an assembly. To

element can appear in multiple partitions and subsets of the product. When
a designer views partitions that may contain the same design element, 4GD

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
recipe opens any new design elements within that volume.
