Hello

I have to make a technical schematics with blocks linked to another blocks.

Each block contains schematics of servers interconnected. each block fit on a A4 page. If I put all blocks next to each other, it will not fit to an A1 sheet, and there will be interconnect everywhere, so too big and not readable.

So, I would like to keep each A4 size block in a separate sheet, and make an overall sheet with display each block as a square, interconnected by lines. clicking on a square would open the sheet

could you help on how to do that ?
suggestions welcome

thanks for help
Mickey
