第四代设计（4GD）管理系统的优势

mildcat

4GD has several advantages over previous generations of data management systems:
• Flexible organization of design data
  O8 A, |- B7 n" lThe collaborative design content can change dynamically as the design evolves.

9 N( T- b2 G5 g3 B+ S6 k• 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.
1 `/ v( ]: V/ X& l4 O# A% \7 X* HLikewise, 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
; V, C: Y1 q5 Y; `/ ^a designer views partitions that may contain the same design element, 4GD
displays only the unique design elements.

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

• Minimal data locking

• Concurrent work capabilities
Because designers access the design elements in their workset using a dynamic
recipe instead of a rigid subassembly, the context of the workset can be updated
to include new design elements created by other designers. For example, if the
