Description

technical field [0001] The invention belongs to the field of building information processing, in particular to a device for quickly establishing a three-dimensional building information model. Background technique [0002] With the rapid development of the construction industry, the demand for construction products with high quality, short construction period and low cost is increasing, which also puts forward higher requirements for architectural design. Building information modeling simulates buildings through 3D digital simulation, and uses high-precision 3D models and construction process control, which can significantly improve design efficiency and model quality. However, in the traditional construction industry, due to historical reasons and technical limitations, the 2D design environment is widely used in architectural design, during which a huge amount of 2D design drawings were produced, and the 2D drawings are mainly drawings that lack architectural information. ...

Problems solved by technology

This solution has the following technical defects: it cannot provide a complete function of editing the 3D model, and the effect of the generated model cannot fully meet the requirements, resulting in the need to manually build a fine 3D model, and the interrelationship between the 3D components cannot be guaranteed; Dimensions cannot meet the requirements of custom building components in the architectural design process; due to the limitation of the 3D editing function of the 2D platform, the solution generally has a fixed and closed product library, using a fixed 3D model, which cannot meet the flexible and changeable architectural design requirements. requirements

This solution does not implement a complete technical process, and it relies on other software to realize the process of extracting architectural information from two-dimensional information, which is limited to a conversion from two-dimensional drawings to three-dimensional modeling, which cannot be popularized and applied, which greatly limits the user's experience use

Moreover, this solution is limited by the extraction method, cannot extract more shapes, and only supports the restoration of components with fixed shapes, and the degree of restoration is insufficient
