export to dwg - some help with the settings

I Have a file with:

  • Drawing Model: with external references attached;
  • Sheet Model: with the internal Drawing model attached, as well as soms external references.

The desired resulting dwg-file should be:

  • model space: the Drawing model with all references merged;
  • paper space: all external references merged, but the Drawing Model still a reference.

That way I have a file with no external references, but keeping the internal references as references.

I have done this before, but seem to struggle to do this again, any help on the dwg-export settings?
