第四代设计（4GD）管理系统的优势

4GD has several advantages over previous generations of data management systems:
* g! h6 B8 u" ]8 O/ t% v% G4 @• Flexible organization of design data

3 \# F) F' Q5 S3 i$ zDesigners are not limited to viewing the product in predefined subassemblies.
• Independent lifecycles
* y0 @' X; B3 ^) xEach design element has its own lifecycle. You are not limited by the lifecycle

• Multiple hierarchical views
, u7 z- n& f- eIn 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
displays only the unique design elements.
• Very large data sets
Because there is no concept of a structure, very large data sets can be managed

traditional assemblies.

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

recipe opens any new design elements within that volume.
