第四代设计（4GD）管理系统的优势

4GD has several advantages over previous generations of data management systems:

• Multiple hierarchical views
In a traditional product structure, each component is placed in an assembly. To
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
a designer views partitions that may contain the same design element, 4GD

Designers check out only the design elements they need. To reposition a design
element, there is no parent assembly to check out and lock.
