How to Draw an object at full scale and then "shrink" to fit A4 while keeping dimensions

Hi,

So this is one of those problems which im sure has an easy answer.

I make sculptures and I want to do a design at full scale to use the new 'dimensions' feature. I want to then scale the whole design down to A4 but keep the 'dimensions' the same ie if a side is 2000mm I want the a4 scale to show 2000mm. I guess I can save the design as a png then paste it onto a new artboard?

Is it possible to set dimsnions to a ratio eg  1: 10 then I can draw on an A4 sized artboard to scale?

thanks,

Jake
