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 B0 r; T: Y' q" t7 z1 B" s• Flexible organization of design data
6 q9 T( n' z3 M& q) C8 w0 Q8 TThe 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
view a component, you must load its parent assembly. Using 4GD, a design

a designer views partitions that may contain the same design element, 4GD

Designers check out only the design elements they need. To reposition a design

• Concurrent work capabilities
& C# u" m( A7 tBecause 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.
