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.

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.

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

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

• Concurrent work capabilities
Because designers access the design elements in their workset using a dynamic

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.
