Method for penetrating through whole decoration design process by using BIM (Building Information Modeling) technology

The invention discloses a method for penetrating a whole decoration design process by using a BIM technology. The method comprises the following steps: creating a parameterized decoration design family library with a two-dimensional detail drawing group; creating a decoration design project template conforming to drawing specifications; building a building structure model with the model precision of LOD300; a scheme model with the model precision being LOD350 is manufactured; converting the scheme model into a corresponding format model suitable for effect picture rendering software; performing 3D rendering to output an effect picture; building a construction drawing model with the model precision of LOD400; and horizontally and vertically sectioning each single body, each floor and each function partition to obtain a graph, and meanwhile, providing a detailed node graph with detailed parts. The method solves the problems that in a traditional design process, communication of design concepts is not smooth, a
