第四代设计（4GD）管理系统的优势

4GD has several advantages over previous generations of data management systems:
% `% @  T' t8 J! j6 f+ a' Q• Flexible organization of design data
) s: i# D. C5 B! z; J: pThe 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.
0 H+ _1 `0 \, ?8 q+ fLikewise, the CAD design owns its position and geometry.
• 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

• Minimal data locking
Designers check out only the design elements they need. To reposition a design

recipe opens any new design elements within that volume.
