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

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.

element can appear in multiple partitions and subsets of the product. When
a designer views partitions that may contain the same design element, 4GD

• 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
traditional assemblies.

element, there is no parent assembly to check out and lock.
• Efficient working sets

the next highest parent assembly that contains all the design elements.
• 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
