Three-dimensional building model management system and method thereof

The present invention relates to a three-dimensional building model management system and a method thereof; in particular, the three-dimensional building model management system of the present invention can automatically obtain a three-dimensional figure corresponding to a floor plan type.

Building Information Modeling (BIM) is a building that represents entities in terms of digital architectural elements. In recent years, BIM's technology and software have gradually matured, enabling relevant units to directly use the built-up BIM model to produce relevant 2D floor plan and BIM model information. However, under the current BIM operation mode, each participating unit obtains the 2D plan view produced by the BIM model. Only the traditional CAD method can be used to check the view information. If the relevant BIM model information is to be referred to, it must still be managed with the BIM model. The unit has obtained engineering information requirements. In the complicated information request process, the unit is not willing to use the BIM model, and the BIM model data and 3D visualization characteristics cannot be fully utilized.

In addition, in the engineering project, the engineering drawing is an important basis for the participating units to confirm the engineering information, and the number of drawings is different depending on the scale of the project. When the scale of the project is huge, the number of engineering drawings is less than a hundred and a thousand, and the problem of the illustrated version is often caused by the design change, which makes it difficult for the management unit to manage the drawing documents effectively. Due to the large number of pictures, the participating units have to spend a lot of time looking for relevant pictures, which is not only time-consuming but also impossible to confirm whether the picture found is the latest version.

An object of the present invention is to provide a three-dimensional building model management system that associates floor plans and solid figures to increase convenience.

Another object of the present invention is to provide a three-dimensional building model management system that can obtain the latest version information and provide problem feedback to save work time.

The host side of the three-dimensional building model management system comprises a floor plan generating module, a stereo graphic generating module and a bar code generating module. The plan view generation module generates a plan view from a preset plane in the three-dimensional building model. The barcode generation module generates a code according to the plan view. The three-dimensional graphics generation module selects a local range of the three-dimensional architectural model according to the preset plane to generate a three-dimensional graphic corresponding to the plan view. The user end includes a barcode reading system, which can read the barcode from the plan view and then transmit the corresponding barcode information to the host end to obtain the corresponding three-dimensional graphics.

The three-dimensional building model management method includes selecting a preset plane from the three-dimensional building model to generate a floor plan. According to the preset plane and the preset depth, the three-dimensional figure corresponding to the plan view is generated from the three-dimensional building model. The self-planar generation module captures the floor plan recognition and generates a bar code in the corresponding floor plan. The user side transmits the barcode information after reading the barcode. The stereoscopic graphics call module determines bar code information. The corresponding stereoscopic graphic is identified by searching the floor plan according to the graphic association form. Obtain a stereoscopic image through the data input and output interface.
