With the continuous progress of science and technology, computers have been continuously developed in all walks of life, architectural design has gradually used new technologies to improve and innovate technology, computer-aided design acid and alkali have been applied in architectural design and planning, and computer-aided architectural design software plays an increasingly important role in architectural design and planning. This paper mainly discusses the technical research and development of computer-aided architectural design software, including software design methods, intelligent technology applications, virtual reality technology applications, etc. By analyzing the characteristics and shortcomings of existing computer-aided architectural design software, this paper proposes a new architectural design software design scheme, and expounds its technology research and development. In order to provide theoretical basis and practical significance for the construction industry.
