I have a huge map made in Illustrator. I made 30 artboards in this map and would like to make an .ai file from each artboard in order to work with smaller files. But each time I save using .ai and chose "use artboard", every artboard is saved with every element of the original file and weights the same size.
How can I save artboard to .ai format with it's content only ?
Here's a screen cap to illustrate : black stroke box is the artboard I want to export in illustrator format without the elements outside it. I don't mean "hide' this elements but really remove them
