Embodiment Construction

[0026] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0027] The protection scope of the present invention is not limited only to the description of this embodiment.

[0028] An earth-rock dam information modeling method based on VB and CATIA, such as figure 1 The flow shown, the specific steps are as follows:

[0029] Step 1: Based on the existing topographic and geological data, establish Figure 4 The 3D terrain model shown in 5:

[0030] Extract the coordinate points of the contour line according to the existing topographic map, then import all the coordinate points into CATIA and fit them into a surface, and use the surface as a limit to generate a 3D terrain model.

[0031] Step 2. Associate VB and CATIA:

[0032] Reference the relevant CATIA library files in VB as needed, and associate VB and CATIA through codes to realize the parameter connection between VB and CATIA, so as to ensure that ...

Abstract

The invention discloses an informatization modeling method for an earth-rockfill dam based on VB and CATIA. Secondary development is carried out on the basis of the VB language and the CATIA, the VB calls the CATIA, and modeling is carried out. The modeling method comprises the following steps of establishing a three-dimensional terrain model on the basis of existing topographic and geological data; linking the VB with the CATIA; designing a VB interface comprising location control parameters and shape control parameters in the VB; writing codes in the VB and creating a dam axis according to endpoint coordinates of the ends of the dam axis; writing codes in the VB and completing design of a dam body; running a program, inputting the parameters, and generating a model. A traditional design mode is abstract in expression and poor in error-correcting capability, and greatly limits improvement of design efficiency. According to the informatization modeling method based on the VB and the CATIA, the characteristics of secondary development, parameterization and three-dimensional visualization of software are utilized, the disadvantage of the traditional water conservancy project design mode can be avoided, and the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of computer-aided design of water conservancy projects, in particular to a modeling method for earth-rock dams with oblique core walls based on VB (Visual Basic) and CATIA. Background technique [0002] After the world's first computer came out, computer technology developed at an astonishing speed. Computer-aided design (CAD) technology has been deeply applied to related fields, and traditional drawing with rulers and compasses has basically withdrawn from the stage of history. Today, with the maturity of computer technology, two-dimensional CAD technology has also been widely used in water conservancy industry engineering. The current design pattern is highly mature, has complete drawing specifications, and each object does not contain model information, and there is no logical relationship between objects, so the design method is simple, but its intuition and error correction ability are poor, and editing...
