slab layout for computer?

I am looking for a program that can take the size of a slab where I can put all the sizes of the Counter (http://GialloFiorito.com) tops to figure out the best use of the Stone (http://g603.net) . Is there any programs out there that anyone is aware of for this purpose? any over the Counter (http://GialloFiorito.com) ones that work? ( 3-D architect, home design) thanks!
