Problems solved by technology

Due to the complex structure and large memory usage of each bridge pier model, although the action function of Dassault software has the function of instantiating models in batches, each bridge pier it instantiates is a model reference with the same memory footprint as the template , using this function of Dassault software to instantiate so many pier models in batches not only wastes a lot of database memory, but also slows down the process, seriously affecting the efficiency of BIM design

Embodiment Construction

[0025] Below, the present invention is described in detail with reference to accompanying drawing and embodiment:

[0026] Such as figure 1 Shown, a kind of method for batch generation bridge pier BIM model is characterized in that: comprise the following steps:

[0027] (i) Build the first-level formwork S1 of the bridge pier

[0028] Analyze the bridges that need to build a BIM model, and summarize the types of piers of the bridge. For each type of pier required, create a bridge pier first-level template and a first-level template data table.

[0029] (ii) Generate pier positioning coordinate system S2

[0030] Establish a bridge layout form, and generate bridge pier positioning coordinate system groups in batches according to the pier position information in the bridge layout form.

[0031] (Ⅲ) Generate the pier secondary formwork S3

[0032] Using the Component Family function of Dassault software, according to the first-level template data table in step (i), decompose...

Abstract

The invention discloses a method for generating BIM models of bridge piers in batches. The bridge pier secondary template established by the present invention is a model reference that occupies memory space, and can be reused by other projects using the same type of pier, and when the secondary template is searched out and placed in the positioning coordinate system, the generated bridge pier model is a A model instance that does not occupy memory. Therefore, compared with the traditional bridge pier modeling method, the present invention has the advantages of high degree of automation, less memory occupation, high modeling efficiency, and reusable template, and can greatly improve the design efficiency and the quality of the results. , has obvious promotion and application value.

Description

technical field [0001] The invention belongs to the technical field of buildings, and in particular relates to a method for generating BIM models of bridge piers in batches. Background technique [0002] Building information modeling is a new tool in architecture, engineering and civil engineering. Building Information Modeling (Building Information Modeling, referred to as BIM), is defined as a building or construction engineering information model that is composed of complete and sufficient information to support life cycle management, and can be directly interpreted by computer applications. In short, it is the life cycle management of the built environment supported by digital technology. [0003] Carrying out bridge design based on BIM technology is the need for deepening and optimizing the design. As an important part of the bridge, bridge piers are numerous in number and in various forms. A super-large bridge may have hundreds of piers of different types and sizes. ...
