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
The collaborative design content can change dynamically as the design evolves.

/ j: V( J: [0 u5 Z& ]% A$ W) J& KEach design element has its own lifecycle. You are not limited by the lifecycle
of traditional assemblies. Each design element has its revision and status.

In a traditional product structure, each component is placed in an assembly. To

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

• Minimal data locking

element, there is no parent assembly to check out and lock.

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

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