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 ]2 b2 E6 ]) X$ oThe collaborative design content can change dynamically as the design evolves.
' k% P0 X, S- B/ v( y$ VDesigners are not limited to viewing the product in predefined subassemblies.
• Independent lifecycles
2 N' `* ~/ `8 p; ?. X  E, iEach design element has its own lifecycle. You are not limited by the lifecycle

Likewise, the CAD design owns its position and geometry.
; u2 e: [7 ~: \4 U0 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

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

Because there is no concept of a structure, very large data sets can be managed
efficiently . Teamcenter loads collaborative designs much more quickly than

to include new design elements created by other designers. For example, if the
