I have assemblies that need to show the assemblies that are around them in an airplane. I have a cabinet that has its own assembly, but also needs to show the seat next to it in a separate configuration for reference. The problem is the seat also has its own assembly and it needs to show the cabinet in a configuration, and someone else could have a bulkhead that needs to show one or both of these in their configurations. This is creating a nightmare of parent/child relations and loops that cause the assemblies to not be able to check in. Any ideas?
