Abstract: The capabilities of 3D digital design and manufacturing have become the core in the competition between enterprises,which are also the backbone and breakthrough point to promote the reformation of developing and manufacturing abilities.Aiming at the problems that 3D process simulation was interpreted as 3D process and the connotation of 3D digital design and manufacturing technology was not grasped correctively in some enterprises,the current demand of domestic 3D design and manufacturing was analyzed,the connotation of  3D digital design and manufacturing technology was elaborated,and the key technologies of 3D digital design and manufacturing were expounded and discussed.By combining with the typical cases analyses,the three-step development strategies of 3D design,3D to process and 3D to equipment for our defense industry enterprises and the two proposals of implementary 3D digital design and manufacturing technology were given.

Key words: product design, three-dimensional process, model-based definition, modeling and simulation, three-dimensional inspection planning, model-based enterprise
