第四代设计（4GD）管理系统的优势

4GD has several advantages over previous generations of data management systems:
/ L8 i% G; M( X  L- q& D& X• Flexible organization of design data
The collaborative design content can change dynamically as the design evolves.
: t% C, j$ g1 K) ^! P4 XDesigners are not limited to viewing the product in predefined subassemblies.
3 S" Y, l5 j. }# A( V• Independent lifecycles
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.

• 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

• 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.

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
