第四代设计（4GD）管理系统的优势

mildcat

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.
Designers are not limited to viewing the product in predefined subassemblies.
; B# a9 v( B  O+ |• Independent lifecycles
3 J: ?% ?9 q; Y# W. n. fEach 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

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
! {3 A0 ~' \  o) F0 Arecipe instead of a rigid subassembly, the context of the workset can be updated
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
