Hull lofting software

I have a serious problem to be solved : I'm now using a ship design software able to manage the whole construction process, from hull lofting to nesting and nc file generation, but it doesn't fully satisfy my needed.
The greater problem I have is to model yacht superstructure where, often, surface modeling capability needed are very strong, or to interface existing surface modeler with the other
Which state-of-the-art software is used in USA to automatize the building process, including drawings?

Thank you for your answer.
