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
4 l  m8 [- X2 v4 |# s. G! d! \, @The collaborative design content can change dynamically as the design evolves.
Designers are not limited to viewing the product in predefined subassemblies.
0 `3 x8 Y( V1 L• Independent lifecycles
Each design element has its own lifecycle. You are not limited by the lifecycle
' f! P3 x. w. _of traditional assemblies. Each design element has its revision and status.
Likewise, the CAD design owns its position and geometry.

5 J  h$ ?  x& N% k( U" uIn 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

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
traditional assemblies.

Designers check out only the design elements they need. To reposition a design

Designers 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
6 E) h6 R! V0 b1 z% o+ W+ ZBecause 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

recipe opens any new design elements within that volume.
