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
) ^9 T0 u" Q1 A# I7 a$ AThe 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
6 G# K" x/ |. `6 L0 Pof traditional assemblies. Each design element has its revision and status.

( s8 P# A5 z( [- _2 H: m• Multiple hierarchical views
, z7 J" c5 `/ O: D2 k/ gIn a traditional product structure, each component is placed in an assembly. To
8 ^( L( L; T' F1 ~4 g3 |5 Zview a component, you must load its parent assembly. Using 4GD, a design
element can appear in multiple partitions and subsets of the product. When
( C3 y+ L0 p: B" w! fa designer views partitions that may contain the same design element, 4GD
displays only the unique design elements.

• Minimal data locking

element, there is no parent assembly to check out and lock.
