Whenever I work on large print documents, I do not have the option to export it to dwg format. I have to re-size the artwork and the copy and paste it into a normal A4 size document and then export the artwork in dwg file. And after I open the file in cad, I have to re-size it again to actual scale.

However when I export, I have an option to exporting the artwork in 1:100 or 1:500, but I don't have the habit of working with scales and it feels inconvenient.
