Looking for the standard practice in MBD for providing background of a larger assembly for locating a group of parts in MBD. An example would be wave linking in faces of the surrounding parts to provide reference for locating dimensions of a group of parts.
We've been using that method with pretty good luck. We found that wave-linking in geometry into an assembly adds a Model reference set (or whatever your default reference set is called). Be aware that this will cause the wave-linked geometry to show in other assemblies. To get around this we made a separate reference set for the wave-linked geometry (we call ours "FOR REFERNCE ONLY"). Then we leave the components that we want shown in the next assembly on the Model reference set (or whatever your default reference set is called). We also go another step further and turn all the wave-linked geometry to a specified color and move it to a specific layer to signify that it is reference.
