第四代设计（4GD）管理系统的优势

4GD has several advantages over previous generations of data management systems:
) c" `/ ~5 L" s( l• Flexible organization of design data
The collaborative design content can change dynamically as the design evolves.
Designers are not limited to viewing the product in predefined subassemblies.

Each design element has its own lifecycle. You are not limited by the lifecycle

Likewise, the CAD design owns its position and geometry.

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

traditional assemblies.
• Minimal data locking
Designers 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

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

to include new design elements created by other designers. For example, if the
recipe searches for all design elements within a spatial volume, reapplying the
recipe opens any new design elements within that volume.
