Copy/paste objects from different layers to other document


How can I copy/paste objects on different layers from one document to another without manually adjusting all the layers?

I have a floorplan in Layout with layers for stramien, text, dimension etc.
But if I copy everything and paste it in another document it all pasts one 1 layer instead of all the different ones from the original file.

Any help?

Thanks in advance!

Copy/paste it layer by layer.
