Adopt Assembly Constraints or Joints and Couplers

Use the Adopt Assembly Constraints or Joints command to automatically create rigid bodies and joints from existing assembly constraints. After you create a motion solution for an assembly, you can use this command to reduce the number of rigid bodies and joints you must manually define.

When you use the command, NX analyzes the assembly and creates the corresponding rigid bodies and joints in the motion solution. You can view a list of all the new rigid groups and joints after they are created.

To avoid unexpected behavior during simulations, you can suppress, delete, or edit created rigid bodies and joints.

Joint type mapping from assembly constraints

The following table shows the joint type that NX tries to create based on the degrees of freedom for the vectors and axes defined in the assembly:

Degrees of freedom	Resultant Basic Joint
0 along or about	Fixed joint or bond joint, depending on the assembly constraint
1 along	Sliding joint
1 about	Hinge joint
1 about, 1 along	Cylindrical joint
3 about	Ball joint
