With the rapid development of digital technology,digital design has become an integral part of the architecture industry.However,there are currently issues such as scattered applications,a plethora of software tool choices,and design collaboration barriers that hinder the sustained application of digitalization.Therefore,establishing a digital design framework based on BIM is an inevitable choice to improve design efficiency and quality.This paper took the digital design framework based on BIM as the research object,explored the current situation and challenges of digital design,and proposed key methods to construct a digital design framework,providing reference for effectively improving the efficiency and quality of digital design,reducing management costs,and achieving the continuous application and optimization of digital design achievements.
