Summary: There are times when a sub-assemblies constraint is best defined in a higher level assembly.
In our businesses example, this would be the lug nuts on a hub assembly. For units shipping without wheels, the nuts need to be constrained to the drum to hold it on. For units shipping with wheels, the lug nuts need to constrained to the wheel flange.
Being able to constrain a sub-component (the lug nut) to another component in the sub-assembly (the drum) at the higher level assembly would resolve this issue.
Description: SolidEdge v19 and newer have this as a possibility.
