[0001] The present invention relates to the technical field of construction decoration project construction management, and specifically to an intelligent management system for interior decoration projects based on BIM. Background Technique

[0002] With the rapid development of computer technology, the emergence of BIM (Building Information Modeling) technology has brought great convenience and benefits to all stages of the building life cycle, such as design, construction, decoration, and maintenance. The building information model establishes a three-dimensional building model that integrates all project information from design to construction through a computer, which can effectively avoid and solve a series of contradictions existing in the current use of CAD to draw two-dimensional drawings, such as low efficiency, difficult to find drawing errors and omissions, repeated drawing, and conflicts between different specialties that are only discovered during construction. It has characteristics such as visualization, collaboration, and information extractability.
