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
2 i- f- h3 `& m1 ]4 A7 }The collaborative design content can change dynamically as the design evolves.
Designers are not limited to viewing the product in predefined subassemblies.

Likewise, the CAD design owns its position and geometry.
2 [# S# q& [% Z: W& r% h• Multiple hierarchical views
In a traditional product structure, each component is placed in an assembly. To

4 _" ]1 ?/ [6 U. F5 |3 sBecause 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
element, there is no parent assembly to check out and lock.

• Concurrent work capabilities

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