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.

1 t" r. r' y; B) k, }3 I• Independent lifecycles
Each 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
In a traditional product structure, each component is placed in an assembly. To

element can appear in multiple partitions and subsets of the product. When
a designer views partitions that may contain the same design element, 4GD
displays only the unique design elements.

Designers check out only the design elements they need. To reposition a design

• Efficient working sets
Designers can work with adjacent design elements, without having to check out
the next highest parent assembly that contains all the design elements.
• Concurrent work capabilities

to include new design elements created by other designers. For example, if the
