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:
# m( U2 O+ V; I) l4 k$ E" U5 l• 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.
• 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.

7 T+ B: l) Y7 o$ v7 K" t, q• 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.

Because designers access the design elements in their workset using a dynamic
recipe instead of a rigid subassembly, the context of the workset can be updated

recipe searches for all design elements within a spatial volume, reapplying the
