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.

• Independent lifecycles
0 y1 R# y3 F" g- hEach design element has its own lifecycle. You are not limited by the lifecycle
of traditional assemblies. Each design element has its revision and status.

• Multiple hierarchical views

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
