Autocad simple Drawing

Hi All, I need some Auto cad drawing for a ground map, its just a imagination of a geometric map for a film shooting studio with all the service and facility side and admin offices, i need a full ground map and then some other drawing for the Air condition system and Electric system map. As i said its just a imagination drawing no need to be within the rules followed in Architecture it just to see how things will take place, Thanks, Fadhel
