Data conversion system from building structure computational analysis model to BIM model

The invention belongs to the field of structural data conversion, particularly relates to a data conversion system from a building structure computational analysis model to a BIM model, and aims to solve the problems that two models do not correspond after multiple modifications, design risks exist, the follow-up speed is low, the construction period is prolonged, and the efficiency is low. The system comprises: a data acquisition module for acquiring structural data of a computational analysis model, the structural data comprising geometric information of a component and a component type; the geometric processing module is used for carrying out geometric processing on the structural data based on component geometric information and the component type to obtain first structural data; the mapping establishing module is used for establishing a mapping relation between the first structure data and the IFC type data; and the data conversion module is used for converting the first building data into IFC type data
