Can you clarify:Yes (to start out, see below) this will be done in single dwg with multiple x-refs, most are nested within an assembly x-ref, and yes I would like to apply the layer settings exactly between the x-refs. All the layer overrides are done in the layout dwg. Most are done in model space, freezing undesired detail (ie. bolts) or changing the color to indicate existing, but there are some in the viewports.

Do you have a single dwg with multiple xrefs and do you want to apply the layer settings used for xref 'A' to the layers of xref 'B'. In other words: Layer B|Layer1 must match A|Layer1.
2.
When you use the word 'overrides' are you referring to viewport layer overrrides or do you mean VISRETAIN overrrides?
