My partner tought me about exporting all the info on layouts in one simple click. copy all the info in layouts( sheet 2-9) to sheet 1, but not exactly on the paper space. Any where on the layout sheet 1 works fine, remember to marque select all the layout sheets one by one and paste it on sheet 1. Finally export the layout sheet 1 to .dwg and he will be able to open that file as a model space in autocad,containing all your data. One thing he may need is to increase the scale by a number k which is the inverse of the scale originally used when sending to layout.and every thing must work as he wants. Hope that helps.
