第四代设计（4GD）管理系统的优势

4GD has several advantages over previous generations of data management systems:
- I, [) F3 g- i% K: B• Flexible organization of design data
1 e7 j9 A1 j( B/ B0 D8 l# N4 J2 hThe collaborative design content can change dynamically as the design evolves.
: M0 A) e. |; \; d: D7 K# mDesigners 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

7 D4 E6 L7 D, y# ?& q• 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

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

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.
