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
: S' O0 X4 R; g, c' MThe collaborative design content can change dynamically as the design evolves.
2 [# d) X+ m7 ]( q- |Designers are not limited to viewing the product in predefined subassemblies.
• Independent lifecycles
# l2 @8 A" ^" J6 q" \4 aEach design element has its own lifecycle. You are not limited by the lifecycle

• Multiple hierarchical views

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

" p% O6 t6 K. x- RBecause 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
8 A1 S/ P& h' m4 b3 h5 }* iDesigners check out only the design elements they need. To reposition a design
element, there is no parent assembly to check out and lock.
• Efficient working sets
. Z, t' D5 @* t( e/ D9 dDesigners can work with adjacent design elements, without having to check out
the next highest parent assembly that contains all the design elements.
• Concurrent work capabilities

recipe instead of a rigid subassembly, the context of the workset can be updated

recipe searches for all design elements within a spatial volume, reapplying the
recipe opens any new design elements within that volume.
