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
" ?4 R( L* B3 f6 Y( _; ^The collaborative design content can change dynamically as the design evolves.
1 s5 a' l8 ^! g* k. M- ]1 x; M5 FDesigners 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.
Likewise, the CAD design owns its position and geometry.
• Multiple hierarchical views
( P+ v) \! z( O; a! P, qIn a traditional product structure, each component is placed in an assembly. To

• Very large data sets

traditional assemblies.
• Minimal data locking

• Concurrent work capabilities
# c# P* _0 _% Q. _1 aBecause 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
to include new design elements created by other designers. For example, if the
