Bridge structure information model system and method for generating 3D and 2D graphics

Abstract

The invention discloses a bridge structure information model system for generating three-dimensional and two-dimensional graphs and a use method thereof. The system comprises a kernel database, an input platform oriented to a designer, a three-dimensional graph processing module and a two-dimensional graph processing module. The kernel database stores bridge structure information through BIM software. The input platform oriented to the designer is used for inputting bridge structure design main control information. The three-dimensional graph processing module and the two-dimensional graph processing module process geometric information of a bridge structure in the kernel database and display the geometric information on a displayer of a computer. During use, the input platform oriented to the designer inputs the information to the kernel database, then the three-dimensional graph processing module and the two-dimensional graph processing module process the data, and three-dimensional or two-dimensional graphs or drawings are output. The defects in the prior art are overcome, and the map making problem of a BIM model is solved.

Description

technical field [0001] The invention relates to the technical field of bridge design, in particular to a bridge structure information model system and a using method for generating three-dimensional graphics and two-dimensional graphics. Background technique [0002] At present, BIM technology in the domestic civil engineering industry is developing rapidly, especially in the field of construction engineering, there have been many successful application cases, such as Shanghai Tower, Shanghai Disneyland, Shanghai Shendu Pumping Station and other large projects, BIM technology in design, construction and operation and maintenance stage played an important role. Existing Autodesk Revit, Tianzheng Construction and other software can realize functions such as fully-associated design based on the core model, design drawing, engineering calculation, construction simulation, etc., and can realize remote dynamic operation and maintenance management through customization and transfor...

Problems solved by technology

Existing BIM software has the functions of establishing 3D models and complete multi-stage information transmission, but it cannot provide finished drawings with annotations for components, let alone finished drawings with annotations for component sections or partial large samples. Manually completed, there is still a "last mile" from the model to the finished product

[0005] However, there are a variety of professional drawing software for bridges on the market. These software have very good two-dimensional drawing design functions (automatic drawing machine), are extremely practical, and are fully capable of meeting the drawing publishing needs of major design institutes. However, they But it does not have the functions of 3D visualization and multi-stage (construction, operation and maintenance) information transmission of the model, and there is a big gap between the vision of "smart city"
