You can use in your Scene Assembly workflows to constrain the position, orientation, or movement of assembly reference nodes and assembly reference members. Members of an assembly reference include nested assembly reference nodes and objects contained by Scene representations. Constraints created on assembly reference nodes and members behave the same way as constraints do when they are created on typical Maya objects and object hierarchies.
When you constrain an assembly reference member, the constraint node appears in the Outliner under the constrained assembly reference members. As with constraints between typical Maya objects, the constraint node is a child of the constrained object. However, in the case of assembly references, the constraint node is not a member of the assembly reference.
