Currently world already entered digital period, the development and prevalence of digital technology and derivatives technology are affecting all areas of life. In the late 20th Century, architectural design field came into digital information epoch. The development of digital technology promotes changes in architectural design, construction and management. By admiring last 30 years architecture works, it is easy to realize that architecture design is influenced by the updating modeling design technologies. Designers increasingly depend on digital design tools. Especially at the beginning of some complex shaped architecture concept design, applying the right technology strategy will directly affect the finish, construction possibility and cost control. Situation was given that the modeling design technology of architecture is at least 20 years behind the manufacturing industry and the employees lack adequate conception of the technical principle, it is hard to avoid the misinterpret and blind faith in modeling technics and being misled by software provider's commercial publicity. From the angle of modeling technology and technologic features, this article introduced how to apply proper modeling technics in architectural design.
