Collaborative Design within Assembly Context

Product design require management of the relationships between components. NX offers tools to simplify the creation, editing of inter-part relationships.

  • Product Interfaces defines geometry that other components can reference
  • WAVE Geometry Linking associatively copies geometry between components
  • WAVE tools simplifies the process of creating and editing inter-part relationships
  • Relations Browser, Sync Links
  • Replacement Assistant

Product Interfaces

Clearly communicating design intent through published interfaces to ensure the correct geometry and expressions are being referenced.
