Unlimited Calculation
With CadnaA you can handle projects of any size. There are practically no limits set by the software. Even projects of huge areas and with billions of objects, sources and grid points can be modeled. However with CadnaA standard version screening calculation is restricted to a maximum 1000 buildings and 1000 screens. With Option XL this restriction is removed and calculations with unlimited numbers of screening objects are possible.
