Abstract: With the flourishing and extensive application of information technology and digital medium, computers will no longer be treated as only tools but medium for displaying design conceptions and operation ways. However, there exist problems as lack of humanistic care and inadequacy of interaction between human and buildings in the fictitious models of comprehensive application of digital media technology of protection of the cultural heritage and development of buildings, computer information engineering and network engineering. The entirely new digital inheritance should do everything possible to truly show the art and cultural information connoted in buildings. The truth of works can be realized through technical means as well as artistic ones.
