NX features all new enhancements for assemblies. New with NX you will find Assembly Joints. This allows users to create relationships between components that are specific to defining the relative motion between components. Joints allow users to constraint assemblies in less time and with fewer constraints. This now produces a constraint network that is easier to understand and can also be directly leveraged by other motion applications.
New joint types include:
These new joint types provide a more intuitive way to define the relaive motion between components. Users are now able to easily distinguish between static and motion based constraints. These new joints for assemblies will reduce the time it takes to constrain an assembly. The other benefit to you is that the entire constraint network will be easier to understand.
