第四代设计（4GD）管理系统的优势

4GD has several advantages over previous generations of data management systems:
; x0 h7 g  d1 g) L3 ^" n, k. U' H• Flexible organization of design data
The collaborative design content can change dynamically as the design evolves.
! A5 c+ T1 d, l; _/ K( j7 CDesigners are not limited to viewing the product in predefined subassemblies.
9 P% r, \8 T- E. J6 h- N9 j• Independent lifecycles
* Y  i# @$ ^- a- HEach design element has its own lifecycle. You are not limited by the lifecycle

Likewise, the CAD design owns its position and geometry.
• Multiple hierarchical views
& H: k2 d8 r' o& |% j4 L4 BIn 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

a designer views partitions that may contain the same design element, 4GD

& ^) e: H. H6 A& m; h• Minimal data locking
