CAD designing may be accurate in designing a accurate model but what happen to the good old days like the old star wars movies.
From the new cgi perspective . The newest stuff doesn't look realistic like the first star wars. They used real models designed with the artists hand without the help of cad. Cad just allows you to design stuff faster and accurate but sometimes the porportions may look right on the computer but doesn't look right in real life model in front of your eyes.
I think the ultimate details is far more superior in 1/48 scale due that it was sculpted and designed in a way by molded clay.
