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
  H  ^( U0 f/ w2 k7 L% V6 vThe collaborative design content can change dynamically as the design evolves.

/ ?: J' \1 p4 G• Independent lifecycles
9 J- i" x( f# \" x7 e8 D3 r* PEach design element has its own lifecycle. You are not limited by the lifecycle

Likewise, the CAD design owns its position and geometry.
• Multiple hierarchical views

element can appear in multiple partitions and subsets of the product. When

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
efficiently . Teamcenter loads collaborative designs much more quickly than

• Minimal data locking

• Efficient working sets

• Concurrent work capabilities

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